Summary

The is_gpt_valid function in fs/partitions/efi.c in the Linux kernel before 2.6.39 does not check the size of an Extensible Firmware Interface (EFI) GUID Partition Table (GPT) entry, which allows physically proximate attackers to cause a denial of service (heap-based buffer overflow and OOPS) or obtain sensitive information from kernel heap memory by connecting a crafted GPT storage device, a different vulnerability than CVE-2011-1577.

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

    descriptionAn updated rhev-hypervisor package that fixes one security issue and several bugs is now available. The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. The rhev-hypervisor package provides a Red Hat Enterprise Virtualization Hypervisor ISO disk image. The Red Hat Enterprise Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine (KVM) hypervisor. It includes everything necessary to run and manage virtual machines: A subset of the Red Hat Enterprise Linux operating environment and the Red Hat Enterprise Virtualization Agent. Note: Red Hat Enterprise Virtualization Hypervisor is only available for the Intel 64 and AMD64 architectures with virtualization extensions. A flaw was found that allowed napi_reuse_skb() to be called on VLAN (virtual LAN) packets. An attacker on the local network could trigger this flaw by sending specially crafted packets to a target system, possibly causing a denial of service. (CVE-2011-1576) Red Hat would like to thank Ryan Sweat for reporting CVE-2011-1576. This updated package provides updated components that include fixes for security issues; however, these issues have no security impact for Red Hat Enterprise Virtualization Hypervisor. These fixes are for bash issue CVE-2008-5374; curl issue CVE-2011-2192; kernel issues CVE-2010-4649, CVE-2011-0695, CVE-2011-0711, CVE-2011-1044, CVE-2011-1182, CVE-2011-1573, CVE-2011-1593, CVE-2011-1745, CVE-2011-1746, CVE-2011-1776, CVE-2011-1780, CVE-2011-1936, CVE-2011-2022, CVE-2011-2213, CVE-2011-2492, CVE-2011-2525, and CVE-2011-2689; libvirt issue CVE-2011-2511; and rsync issue CVE-2007-6200. This update also fixes several bugs. Documentation for these bug fixes will be available shortly from the Technical Notes document linked to in the References section. As Red Hat Enterprise Virtualization Hypervisor is based on KVM, the bug fixes from the KVM update RHBA-2011:1068 have been included in this update : https://rhn.redhat.com/errata/RHBA-2011-1068.html Users of Red Hat Enterprise Virtualization Hypervisor are advised to upgrade to this updated package, which resolves this issue and fixes the bugs noted in the Technical Notes.

    descriptionTimo Warns discovered that the LDM disk partition handling code did not correctly handle certain values. By inserting a specially crafted disk device, a local attacker could exploit this to gain root privileges. (CVE-2011-1017) Neil Horman discovered that NFSv4 did not correctly handle certain orders of operation with ACL data. A remote attacker with access to an NFSv4 mount could exploit this to crash the system, leading to a denial of service. (CVE-2011-1090) Timo Warns discovered that OSF partition parsing routines did not correctly clear memory. A local attacker with physical access could plug in a specially crafted block device to read kernel memory, leading to a loss of privacy. (CVE-2011-1163) Dan Rosenberg discovered that MPT devices did not correctly validate certain values in ioctl calls. If these drivers were loaded, a local attacker could exploit this to read arbitrary kernel memory, leading to a loss of privacy. (CVE-2011-1494, CVE-2011-1495) Tavis Ormandy discovered that the pidmap function did not correctly handle large requests. A local attacker could exploit this to crash the system, leading to a denial of service. (CVE-2011-1593) Oliver Hartkopp and Dave Jones discovered that the CAN network driver did not correctly validate certain socket structures. If this driver was loaded, a local attacker could crash the system, leading to a denial of service. (CVE-2011-1598, CVE-2011-1748) Vasiliy Kulikov discovered that the AGP driver did not check certain ioctl values.

(CVE-2011-1745, CVE-2011-2022) Vasiliy Kulikov discovered that the AGP driver did not check the size of certain memory allocations. A local attacker with access to the video subsystem could exploit this to run the system out of memory, leading to a denial of service. (CVE-2011-1746) Dan Rosenberg reported an error in the old ABI compatibility layer of ARM kernels. A local attacker could exploit this flaw to cause a denial of service or gain root privileges. (CVE-2011-1759) Dan Rosenberg discovered that the DCCP stack did not correctly handle certain packet structures. A remote attacker could exploit this to crash the system, leading to a denial of service. (CVE-2011-1770) Timo Warns discovered that the EFI GUID partition table was not correctly parsed. A physically local attacker that could insert mountable devices could exploit this to crash the system or possibly gain root privileges. (CVE-2011-1776) Yogesh Sharma discovered that CIFS did not correctly handle UNCs that had no prefixpaths.

    descriptionThe SUSE Linux Enterprise 11 Service Pack 1 kernel was updated to 2.6.32.45 and fixes various bugs and security issues. The following security issues have been fixed : - Timo Warns reported an issue in the Linux implementation for GUID partitions. Users with physical access could gain access to sensitive kernel memory by adding a storage device with a specially crafted corrupted invalid partition table. (CVE-2011-1776) - The second part of this fix was not yet applied to our kernel: arch/x86/kvm/x86.c in the Linux kernel before 2.6.36.2 does not initialize certain structure members, which allows local users to obtain potentially sensitive information from kernel stack memory via read operations on the /dev/kvm device. (CVE-2010-3881) - The /proc/PID/io interface could be used by local attackers to gain information on other processes like number of password characters typed or similar. (CVE-2011-2495) - A small buffer overflow in the radio driver si4713-i2c was fixed that could potentially used by local attackers to crash the kernel or potentially execute code. (CVE-2011-2700) - A kernel information leak in the comedi driver from kernel to userspace was fixed. (CVE-2011-2909) - In the perf framework software event overflows could deadlock or delete an uninitialized timer. (CVE-2011-2918)

    descriptionThe openSUSE 11.3 kernel was updated to fix various bugs and security issues. Following security issues have been fixed: CVE-2011-1833: Added a kernel option to ensure ecryptfs is mounting only on paths belonging to the current ui, which would have allowed local attackers to potentially gain privileges via symlink attacks. CVE-2011-3363: Always check the path in CIFS mounts to avoid interesting filesystem path interaction issues and potential crashes. CVE-2011-2918: In the perf framework software event overflows could deadlock or delete an uninitialized timer. CVE-2011-3353: In the fuse filesystem, FUSE_NOTIFY_INVAL_ENTRY did not check the length of the write so the message processing could overrun and result in a BUG_ON() in fuse_copy_fill(). This flaw could be used by local users able to mount FUSE filesystems to crash the system. CVE-2011-3191: A signedness issue in CIFS could possibly have lead to to memory corruption, if a malicious server could send crafted replies to the host. CVE-2011-1776: The is_gpt_valid function in fs/partitions/efi.c in the Linux kernel did not check the size of an Extensible Firmware Interface (EFI) GUID Partition Table (GPT) entry, which allowed physically proximate attackers to cause a denial of service (heap-based buffer overflow and OOPS) or obtain sensitive information from kernel heap memory by connecting a crafted GPT storage device, a different vulnerability than CVE-2011-1577. Following non security bugs were fixed : - drm/radeon/kms: Fix I2C mask definitions (bnc#712023). - ext4: Fix max file size and logical block counting of extent format file (bnc#706374). - TTY: pty, fix pty counting (bnc#711203). - Update Xen patches to 2.6.34.10. - xen/blkfront: fix data size for xenbus_gather in connect(). - xen/xenbus: fix xenbus_transaction_start() hang caused by double xenbus_transaction_end(). - xen/blkback: don

  • NASL familyScientific Linux Local Security Checks
    NASL idSL_20110823_KERNEL_ON_SL6_X.NASL
    descriptionSecurity issues : - Using PCI passthrough without interrupt remapping support allowed KVM guests to generate MSI interrupts and thus potentially inject traps. A privileged guest user could use this flaw to crash the host or possibly escalate their privileges on the host. The fix for this issue can prevent PCI passthrough working and guests starting. (CVE-2011-1898, Important) - Flaw in the client-side NLM implementation could allow a local, unprivileged user to cause a denial of service. (CVE-2011-2491, Important) - Integer underflow in the Bluetooth implementation could allow a remote attacker to cause a denial of service or escalate their privileges by sending a specially crafted request to a target system via Bluetooth. (CVE-2011-2497, Important) - Buffer overflows in the netlink-based wireless configuration interface implementation could allow a local user, who has the CAP_NET_ADMIN capability, to cause a denial of service or escalate their privileges on systems that have an active wireless interface. (CVE-2011-2517, Important) - Flaw in the way the maximum file offset was handled for ext4 file systems could allow a local, unprivileged user to cause a denial of service. (CVE-2011-2695, Important) - Flaw allowed napi_reuse_skb() to be called on VLAN packets. An attacker on the local network could use this flaw to send crafted packets to a target, possibly causing a denial of service. (CVE-2011-1576, Moderate) - Integer signedness error in next_pidmap() could allow a local, unprivileged user to cause a denial of service. (CVE-2011-1593, Moderate) - Race condition in the memory merging support (KSM) could allow a local, unprivileged user to cause a denial of service. KSM is off by default, but on systems running VDSM, or on KVM hosts, it is likely turned on by the ksm/ksmtuned services. (CVE-2011-2183, Moderate) - Flaw in inet_diag_bc_audit() could allow a local, unprivileged user to cause a denial of service. (CVE-2011-2213, Moderate) - Flaw in the way space was allocated in the Global File System 2 (GFS2) implementation. If the file system was almost full, and a local, unprivileged user made an fallocate() request, it could result in a denial of service. Setting quotas to prevent users from using all available disk space would prevent exploitation of this flaw. (CVE-2011-2689, Moderate) - Local, unprivileged users could send signals via the sigqueueinfo system call, with si_code set to SI_TKILL and with spoofed process and user IDs, to other processes. This flaw does not allow existing permission checks to be bypassed; signals can only be sent if your privileges allow you to already do so. (CVE-2011-1182, Low) - Heap overflow in the EFI GUID Partition Table (GPT) implementation could allow a local attacker to cause a denial of service by mounting a disk containing crafted partition tables. (CVE-2011-1776, Low) - Structure padding in two structures in the Bluetooth implementation was not initialized properly before being copied to user-space, possibly allowing local, unprivileged users to leak kernel stack memory to user-space. (CVE-2011-2492, Low) - /proc/[PID]/io is world-readable by default. Previously, these files could be read without any further restrictions. A local, unprivileged user could read these files, belonging to other, possibly privileged processes to gather confidential information, such as the length of a password used in a process.

    titleScientific Linux Security Update : kernel on SL6.x i386/x86_64
  • NASL familySuSE Local Security Checks
    NASL idSUSE_KERNEL-7734.NASL
    descriptionThis kernel update for the SUSE Linux Enterprise 10 SP3 kernel fixes several security issues and bugs. The following security issues have been fixed : - A signedness issue in CIFS could possibly have lead to to memory corruption, if a malicious server could send crafted replies to the host. (CVE-2011-3191) - Timo Warns reported an issue in the Linux implementation for GUID partitions. Users with physical access could gain access to sensitive kernel memory by adding a storage device with a specially crafted corrupted invalid partition table. (CVE-2011-1776) - The dccp_rcv_state_process function in net/dccp/input.c in the Datagram Congestion Control Protocol (DCCP) implementation in the Linux kernel did not properly handle packets for a CLOSED endpoint, which allowed remote attackers to cause a denial of service (NULL pointer dereference and OOPS) by sending a DCCP-Close packet followed by a DCCP-Reset packet. (CVE-2011-1093) - Integer overflow in the agp_generic_insert_memory function in drivers/char/agp/generic.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (system crash) via a crafted AGPIOC_BIND agp_ioctl ioctl call. (CVE-2011-1745) - Multiple integer overflows in the (1) agp_allocate_memory and (2) agp_create_user_memory functions in drivers/char/agp/generic.c in the Linux kernel allowed local users to trigger buffer overflows, and consequently cause a denial of service (system crash) or possibly have unspecified other impact, via vectors related to calls that specify a large number of memory pages. (CVE-2011-1746) - The agp_generic_remove_memory function in drivers/char/agp/generic.c in the Linux kernel before 2.6.38.5 did not validate a certain start parameter, which allowed local users to gain privileges or cause a denial of service (system crash) via a crafted AGPIOC_UNBIND agp_ioctl ioctl call, a different vulnerability than CVE-2011-1745. (CVE-2011-2022) - The do_task_stat function in fs/proc/array.c in the Linux kernel did not perform an expected uid check, which made it easier for local users to defeat the ASLR protection mechanism by reading the start_code and end_code fields in the /proc/#####/stat file for a process executing a PIE binary. (CVE-2011-0726) - The normal mmap paths all avoid creating a mapping where the pgoff inside the mapping could wrap around due to overflow. However, an expanding mremap() can take such a non-wrapping mapping and make it bigger and cause a wrapping condition. (CVE-2011-2496) - A local unprivileged user able to access a NFS filesystem could use file locking to deadlock parts of an nfs server under some circumstance. (CVE-2011-2491) - The code for evaluating LDM partitions (in fs/partitions/ldm.c) contained bugs that could crash the kernel for certain corrupted LDM partitions. (CVE-2011-1017 / CVE-2011-2182) - When using a setuid root mount.cifs, local users could hijack password protected mounted CIFS shares of other local users. (CVE-2011-1585) Also following non-security bugs were fixed : - patches.suse/fs-proc-vmcorec-add-hook-to-read_from_oldme m-to-check-for-non-ram-pages.patch: fs/proc/vmcore.c: add hook to read_from_oldmem() to check for non-ram pages. (bnc#684297) - patches.xen/1062-xenbus-dev-leak.patch: xenbus: Fix memory leak on release. - patches.xen/1074-xenbus_conn-type.patch: xenbus: fix type inconsistency with xenbus_conn(). - patches.xen/1080-blkfront-xenbus-gather-format.patch: blkfront: fix data size for xenbus_gather in connect(). - patches.xen/1081-blkback-resize-transaction-end.patch: xenbus: fix xenbus_transaction_start() hang caused by double xenbus_transaction_end(). - patches.xen/1089-blkback-barrier-check.patch: blkback: dont fail empty barrier requests. - patches.xen/1091-xenbus-dev-no-BUG.patch: xenbus: dont BUG() on user mode induced conditions.

    NASL idSUSE_11_4_KERNEL-111026.NASL
    descriptionThe openSUSE 11.4 kernel was updated to 2.6.37.6 fixing lots of bugs and security issues. Following security issues have been fixed: CVE-2011-1833: Added a kernel option to ensure ecryptfs is mounting only on paths belonging to the current ui, which would have allowed local attackers to potentially gain privileges via symlink attacks. CVE-2011-2695: Multiple off-by-one errors in the ext4 subsystem in the Linux kernel allowed local users to cause a denial of service (BUG_ON and system crash) by accessing a sparse file in extent format with a write operation involving a block number corresponding to the largest possible 32-bit unsigned integer. CVE-2011-3363: Always check the path in CIFS mounts to avoid interesting filesystem path interaction issues and potential crashes. CVE-2011-2918: In the perf framework software event overflows could deadlock or delete an uninitialized timer. CVE-2011-3353: In the fuse filesystem, FUSE_NOTIFY_INVAL_ENTRY did not check the length of the write so the message processing could overrun and result in a BUG_ON() in fuse_copy_fill(). This flaw could be used by local users able to mount FUSE filesystems to crash the system. CVE-2011-2183: Fixed a race between ksmd and other memory management code, which could result in a NULL ptr dereference and kernel crash. CVE-2011-3191: A signedness issue in CIFS could possibly have lead to to memory corruption, if a malicious server could send crafted replies to the host. CVE-2011-1776: The is_gpt_valid function in fs/partitions/efi.c in the Linux kernel did not check the size of an Extensible Firmware Interface (EFI) GUID Partition Table (GPT) entry, which allowed physically proximate attackers to cause a denial of service (heap-based buffer overflow and OOPS) or obtain sensitive information from kernel heap memory by connecting a crafted GPT storage device, a different vulnerability than CVE-2011-1577. Following non-security bugs were fixed : - novfs: Unable to change password in the Novell Client for Linux (bnc#713229). - novfs: last modification time not reliable (bnc#642896). - novfs: unlink directory after unmap (bnc#649625). - fs: novfs: Fix exit handlers on local_unlink (bnc#649625). - novfs:

  • NASL familySuSE Local Security Checks
    NASL idSUSE_KERNEL-7729.NASL
    descriptionThis kernel update for the SUSE Linux Enterprise 10 SP3 kernel fixes several security issues and bugs. The following security issues have been fixed : - A signedness issue in CIFS could possibly have lead to to memory corruption, if a malicious server could send crafted replies to the host. (CVE-2011-3191) - Timo Warns reported an issue in the Linux implementation for GUID partitions. Users with physical access could gain access to sensitive kernel memory by adding a storage device with a specially crafted corrupted invalid partition table. (CVE-2011-1776) - The dccp_rcv_state_process function in net/dccp/input.c in the Datagram Congestion Control Protocol (DCCP) implementation in the Linux kernel did not properly handle packets for a CLOSED endpoint, which allowed remote attackers to cause a denial of service (NULL pointer dereference and OOPS) by sending a DCCP-Close packet followed by a DCCP-Reset packet. (CVE-2011-1093) - Integer overflow in the agp_generic_insert_memory function in drivers/char/agp/generic.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (system crash) via a crafted AGPIOC_BIND agp_ioctl ioctl call. (CVE-2011-1745) - Multiple integer overflows in the (1) agp_allocate_memory and (2) agp_create_user_memory functions in drivers/char/agp/generic.c in the Linux kernel allowed local users to trigger buffer overflows, and consequently cause a denial of service (system crash) or possibly have unspecified other impact, via vectors related to calls that specify a large number of memory pages. (CVE-2011-1746) - The agp_generic_remove_memory function in drivers/char/agp/generic.c in the Linux kernel before 2.6.38.5 did not validate a certain start parameter, which allowed local users to gain privileges or cause a denial of service (system crash) via a crafted AGPIOC_UNBIND agp_ioctl ioctl call, a different vulnerability than CVE-2011-1745. (CVE-2011-2022) - The do_task_stat function in fs/proc/array.c in the Linux kernel did not perform an expected uid check, which made it easier for local users to defeat the ASLR protection mechanism by reading the start_code and end_code fields in the /proc/#####/stat file for a process executing a PIE binary. (CVE-2011-0726) - The normal mmap paths all avoid creating a mapping where the pgoff inside the mapping could wrap around due to overflow. However, an expanding mremap() can take such a non-wrapping mapping and make it bigger and cause a wrapping condition. (CVE-2011-2496) - A local unprivileged user able to access a NFS filesystem could use file locking to deadlock parts of an nfs server under some circumstance. (CVE-2011-2491) - The code for evaluating LDM partitions (in fs/partitions/ldm.c) contained bugs that could crash the kernel for certain corrupted LDM partitions. (CVE-2011-1017 / CVE-2011-2182) - When using a setuid root mount.cifs, local users could hijack password protected mounted CIFS shares of other local users. (CVE-2011-1585) Also following non-security bugs were fixed : - patches.suse/fs-proc-vmcorec-add-hook-to-read_from_oldme m-to-check-for-non-ram-pages.patch: fs/proc/vmcore.c: add hook to read_from_oldmem() to check for non-ram pages. (bnc#684297) - patches.xen/1062-xenbus-dev-leak.patch: xenbus: Fix memory leak on release. - patches.xen/1074-xenbus_conn-type.patch: xenbus: fix type inconsistency with xenbus_conn(). - patches.xen/1080-blkfront-xenbus-gather-format.patch: blkfront: fix data size for xenbus_gather in connect(). - patches.xen/1081-blkback-resize-transaction-end.patch: xenbus: fix xenbus_transaction_start() hang caused by double xenbus_transaction_end(). - patches.xen/1089-blkback-barrier-check.patch: blkback: dont fail empty barrier requests. - patches.xen/1091-xenbus-dev-no-BUG.patch: xenbus: dont BUG() on user mode induced conditions. (bnc#696107) - patches.xen/1098-blkfront-cdrom-ioctl-check.patch: blkfront: avoid NULL de-reference in CDROM ioctl handling. (bnc#701355) - patches.xen/1102-x86-max-contig-order.patch: x86: use dynamically adjusted upper bound for contiguous regions. (bnc#635880) - patches.xen/xen3-x86-sanitize-user-specified-e820-memmap -values.patch: x86: sanitize user specified e820 memmap values. (bnc#665543) - patches.fixes/libiscsi-dont-run-scsi-eh-if-iscsi-task-is -making-progress: Fix typo, which was uncovered in debug mode. - patches.fixes/pacct-fix-sighand-siglock-usage.patch: Fix sighand->siglock usage in kernel/acct.c.

  • NASL familyRed Hat Local Security Checks
    NASL idREDHAT-RHSA-2011-1189.NASL
    descriptionUpdated kernel packages that fix several security issues, various bugs, and add two enhancements are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. Security issues : * Using PCI passthrough without interrupt remapping support allowed KVM guests to generate MSI interrupts and thus potentially inject traps. A privileged guest user could use this flaw to crash the host or possibly escalate their privileges on the host. The fix for this issue can prevent PCI passthrough working and guests starting. Refer to Red Hat Bugzilla bug 715555 for details. (CVE-2011-1898, Important) * Flaw in the client-side NLM implementation could allow a local, unprivileged user to cause a denial of service. (CVE-2011-2491, Important) * Integer underflow in the Bluetooth implementation could allow a remote attacker to cause a denial of service or escalate their privileges by sending a specially crafted request to a target system via Bluetooth. (CVE-2011-2497, Important) * Buffer overflows in the netlink-based wireless configuration interface implementation could allow a local user, who has the CAP_NET_ADMIN capability, to cause a denial of service or escalate their privileges on systems that have an active wireless interface. (CVE-2011-2517, Important) * Flaw in the way the maximum file offset was handled for ext4 file systems could allow a local, unprivileged user to cause a denial of service. (CVE-2011-2695, Important) * Flaw allowed napi_reuse_skb() to be called on VLAN packets. An attacker on the local network could use this flaw to send crafted packets to a target, possibly causing a denial of service. (CVE-2011-1576, Moderate) * Integer signedness error in next_pidmap() could allow a local, unprivileged user to cause a denial of service. (CVE-2011-1593, Moderate) * Race condition in the memory merging support (KSM) could allow a local, unprivileged user to cause a denial of service. KSM is off by default, but on systems running VDSM, or on KVM hosts, it is likely turned on by the ksm/ksmtuned services. (CVE-2011-2183, Moderate) * Flaw in inet_diag_bc_audit() could allow a local, unprivileged user to cause a denial of service. (CVE-2011-2213, Moderate) * Flaw in the way space was allocated in the Global File System 2 (GFS2) implementation. If the file system was almost full, and a local, unprivileged user made an fallocate() request, it could result in a denial of service. Setting quotas to prevent users from using all available disk space would prevent exploitation of this flaw. (CVE-2011-2689, Moderate) * Local, unprivileged users could send signals via the sigqueueinfo system call, with si_code set to SI_TKILL and with spoofed process and user IDs, to other processes. This flaw does not allow existing permission checks to be bypassed; signals can only be sent if your privileges allow you to already do so. (CVE-2011-1182, Low) * Heap overflow in the EFI GUID Partition Table (GPT) implementation could allow a local attacker to cause a denial of service by mounting a disk containing crafted partition tables. (CVE-2011-1776, Low) * Structure padding in two structures in the Bluetooth implementation was not initialized properly before being copied to user-space, possibly allowing local, unprivileged users to leak kernel stack memory to user-space. (CVE-2011-2492, Low) * /proc/[PID]/io is world-readable by default. Previously, these files could be read without any further restrictions. A local, unprivileged user could read these files, belonging to other, possibly privileged processes to gather confidential information, such as the length of a password used in a process. (CVE-2011-2495, Low) Red Hat would like to thank Vasily Averin for reporting CVE-2011-2491; Dan Rosenberg for reporting CVE-2011-2497 and CVE-2011-2213; Ryan Sweat for reporting CVE-2011-1576; Robert Swiecki for reporting CVE-2011-1593; Andrea Righi for reporting CVE-2011-2183; Julien Tinnes of the Google Security Team for reporting CVE-2011-1182; Timo Warns for reporting CVE-2011-1776; Marek Kroemeke and Filip Palian for reporting CVE-2011-2492; and Vasiliy Kulikov of Openwall for reporting CVE-2011-2495.

    NASL idORACLELINUX_ELSA-2011-1189.NASL
    descriptionFrom Red Hat Security Advisory 2011:1189 : Updated kernel packages that fix several security issues, various bugs, and add two enhancements are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. Security issues : * Using PCI passthrough without interrupt remapping support allowed KVM guests to generate MSI interrupts and thus potentially inject traps. A privileged guest user could use this flaw to crash the host or possibly escalate their privileges on the host. The fix for this issue can prevent PCI passthrough working and guests starting. Refer to Red Hat Bugzilla bug 715555 for details. (CVE-2011-1898, Important) * Flaw in the client-side NLM implementation could allow a local, unprivileged user to cause a denial of service. (CVE-2011-2491, Important) * Integer underflow in the Bluetooth implementation could allow a remote attacker to cause a denial of service or escalate their privileges by sending a specially crafted request to a target system via Bluetooth. (CVE-2011-2497, Important) * Buffer overflows in the netlink-based wireless configuration interface implementation could allow a local user, who has the CAP_NET_ADMIN capability, to cause a denial of service or escalate their privileges on systems that have an active wireless interface. (CVE-2011-2517, Important) * Flaw in the way the maximum file offset was handled for ext4 file systems could allow a local, unprivileged user to cause a denial of service. (CVE-2011-2695, Important) * Flaw allowed napi_reuse_skb() to be called on VLAN packets. An attacker on the local network could use this flaw to send crafted packets to a target, possibly causing a denial of service. (CVE-2011-1576, Moderate) * Integer signedness error in next_pidmap() could allow a local, unprivileged user to cause a denial of service. (CVE-2011-1593, Moderate) * Race condition in the memory merging support (KSM) could allow a local, unprivileged user to cause a denial of service. KSM is off by default, but on systems running VDSM, or on KVM hosts, it is likely turned on by the ksm/ksmtuned services. (CVE-2011-2183, Moderate) * Flaw in inet_diag_bc_audit() could allow a local, unprivileged user to cause a denial of service. (CVE-2011-2213, Moderate) * Flaw in the way space was allocated in the Global File System 2 (GFS2) implementation. If the file system was almost full, and a local, unprivileged user made an fallocate() request, it could result in a denial of service. Setting quotas to prevent users from using all available disk space would prevent exploitation of this flaw. (CVE-2011-2689, Moderate) * Local, unprivileged users could send signals via the sigqueueinfo system call, with si_code set to SI_TKILL and with spoofed process and user IDs, to other processes. This flaw does not allow existing permission checks to be bypassed; signals can only be sent if your privileges allow you to already do so. (CVE-2011-1182, Low) * Heap overflow in the EFI GUID Partition Table (GPT) implementation could allow a local attacker to cause a denial of service by mounting a disk containing crafted partition tables. (CVE-2011-1776, Low) * Structure padding in two structures in the Bluetooth implementation was not initialized properly before being copied to user-space, possibly allowing local, unprivileged users to leak kernel stack memory to user-space. (CVE-2011-2492, Low) * /proc/[PID]/io is world-readable by default. Previously, these files could be read without any further restrictions. A local, unprivileged user could read these files, belonging to other, possibly privileged processes to gather confidential information, such as the length of a password used in a process. (CVE-2011-2495, Low) Red Hat would like to thank Vasily Averin for reporting CVE-2011-2491; Dan Rosenberg for reporting CVE-2011-2497 and CVE-2011-2213; Ryan Sweat for reporting CVE-2011-1576; Robert Swiecki for reporting CVE-2011-1593; Andrea Righi for reporting CVE-2011-2183; Julien Tinnes of the Google Security Team for reporting CVE-2011-1182; Timo Warns for reporting CVE-2011-1776; Marek Kroemeke and Filip Palian for reporting CVE-2011-2492; and Vasiliy Kulikov of Openwall for reporting CVE-2011-2495.
