Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Leveraging Race Conditions
    This attack targets a race condition occurring when multiple processes access and manipulate the same resource concurrently and the outcome of the execution depends on the particular order in which the access takes place. The attacker can leverage a race condition by "running the race", modifying the resource and modifying the normal execution flow. For instance a race condition can occur while accessing a file, the attacker can trick the system by replacing the original file with his version and cause the system to read the malicious file.
  • Leveraging Time-of-Check and Time-of-Use (TOCTOU) Race Conditions
    This attack targets a race condition occurring between the time of check (state) for a resource and the time of use of a resource. The typical example is the file access. The attacker can leverage a file access race condition by "running the race", meaning that he would modify the resource between the first time the target program accesses the file and the time the target program uses the file. During that period of time, the attacker could do something such as replace the file and cause an escalation of privilege.

local user to cause a denial of service (system hang). (CVE-2006-4814,
Moderate)

* it was discovered that the Linux kernel handled string operations in
the opposite way to the GNU Compiler Collection (GCC). This could
allow a local unprivileged user to cause memory corruption.
(CVE-2008-1367, Low)

As well, these updated packages fix the following bugs :

* a bug, which caused long delays when unmounting mounts containing a
large number of unused dentries, has been resolved.

* in the previous kernel packages, the kernel was unable to handle
certain floating point instructions on Itanium(R) architectures.

* on certain Intel CPUs, the Translation Lookaside Buffer (TLB) was
not flushed correctly, which caused machine check errors.

Red Hat Enterprise Linux 3 users are advised to upgrade to these
updated packages, which contain backported patches to resolve these
issues."

stress-test File Transfer Protocol (FTP) transfer between the guest
and the hypervisor, possibly leading to hypervisor panic.
(CVE-2008-1619, Important)

registering a fault handler did not perform required range checks. A
local unprivileged user could use this flaw to gain read or write
access to arbitrary kernel memory, or possibly cause a kernel crash.

and as such, they have not been handled as security issues.

* when running Microsoft Windows in a HVM, a bug in vmalloc/vfree
caused network performance to degrade.

* on certain architectures, a bug in the libATA sata_nv driver may
have caused infinite reboots, and an 'ata1: CPB flags CMD err flags
0x11' error.

* repeatedly hot-plugging a PCI Express card may have caused 'Bad
DLLP' errors.

* a NULL pointer dereference in NFS, which may have caused
applications to crash, has been resolved.

* when attempting to kexec reboot, either manually or via a
panic-triggered kdump, the Unisys ES7000/one hanged after rebooting in
the new kernel, after printing the 'Memory: 32839688k/33685504k

  - A ptrace bug could be used by local attackers to hang
    their own processes indefinitely. (CVE-2007-5500)

  - Clear the 'direction' flag before calling signal
    handlers. For specific not yet identified programs under
    specific timing conditions this could potentially have
    caused memory corruption or code execution.
    (CVE-2008-1367)

  - The isdn_ioctl function in isdn_common.c allowed local
    users to cause a denial of service via a crafted ioctl
    struct in which ioctls is not null terminated, which
    triggers a buffer overflow. (CVE-2007-6151)

Non security related changes :

OCFS2 was updated to version v1.2.9-1-r3100.

Also a huge number of bugs were fixed. Please refer to the
RPM changelog for a detailed list."

"Updated kernel packages that fix various security issues and several
bugs are now available for Red Hat Enterprise Linux 4.

This update has been rated as having important security impact by the
Red Hat Security Response Team.

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

These updated packages fix the following security issues :

* the absence of a protection mechanism when attempting to access a
critical section of code has been found in the Linux kernel open file
descriptors control mechanism, fcntl. This could allow a local
unprivileged user to simultaneously execute code, which would
otherwise be protected against parallel execution. As well, a race
condition when handling locks in the Linux kernel fcntl functionality,
may have allowed a process belonging to a local unprivileged user to
gain re-ordered access to the descriptor table. (CVE-2008-1669,
Important)

* on AMD64 architectures, the possibility of a kernel crash was
discovered by testing the Linux kernel process-trace ability. This
could allow a local unprivileged user to cause a denial of service
(kernel crash). (CVE-2008-1615, Important)

* the absence of a protection mechanism when attempting to access a
critical section of code, as well as a race condition, have been found
in the Linux kernel file system event notifier, dnotify. This could
allow a local unprivileged user to get inconsistent data, or to send
arbitrary signals to arbitrary system processes. (CVE-2008-1375,
Important)

Red Hat would like to thank Nick Piggin for responsibly disclosing the
following issue :

* when accessing kernel memory locations, certain Linux kernel drivers
registering a fault handler did not perform required range checks. A
local unprivileged user could use this flaw to gain read or write
access to arbitrary kernel memory, or possibly cause a kernel crash.
(CVE-2008-0007, Important)

* the possibility of a kernel crash was found in the Linux kernel
IPsec protocol implementation, due to improper handling of fragmented
ESP packets. When an attacker controlling an intermediate router
fragmented these packets into very small pieces, it would cause a
kernel crash on the receiving node during packet reassembly.
(CVE-2007-6282, Important)

* a flaw in the MOXA serial driver could allow a local unprivileged
user to perform privileged operations, such as replacing firmware.
(CVE-2005-0504, Important)

As well, these updated packages fix the following bugs :

* multiple buffer overflows in the neofb driver have been resolved. It
was not possible for an unprivileged user to exploit these issues, and
as such, they have not been handled as security issues.

* a kernel panic, due to inconsistent detection of AGP aperture size,
has been resolved.

* a race condition in UNIX domain sockets may have caused 'recv()' to
return zero. In clustered configurations, this may have caused
unexpected failovers.

* to prevent link storms, network link carrier events were delayed by
up to one second, causing unnecessary packet loss. Now, link carrier
events are scheduled immediately.

* a client-side race on blocking locks caused large time delays on NFS
file systems.

* in certain situations, the libATA sata_nv driver may have sent
commands with duplicate tags, which were rejected by SATA devices.
This may have caused infinite reboots.

* running the 'service network restart' command may have caused
networking to fail.

* a bug in NFS caused cached information about directories to be
stored for too long, causing wrong attributes to be read.

* on systems with a large highmem/lowmem ratio, NFS write performance
may have been very slow when using small files.

* a bug, which caused network hangs when the system clock was wrapped
around zero, has been resolved.

Red Hat Enterprise Linux 4 users are advised to upgrade to these
updated packages, which contain backported patches to resolve these
issues."

    descriptionFrom Red Hat Security Advisory 2008:0237 : Updated kernel packages that fix various security issues and several bugs are now available for Red Hat Enterprise Linux 4. This update has been rated as having important security impact by the Red Hat Security Response Team. The kernel packages contain the Linux kernel, the core of any Linux operating system. These updated packages fix the following security issues : * the absence of a protection mechanism when attempting to access a critical section of code has been found in the Linux kernel open file descriptors control mechanism, fcntl. This could allow a local unprivileged user to simultaneously execute code, which would otherwise be protected against parallel execution. As well, a race condition when handling locks in the Linux kernel fcntl functionality, may have allowed a process belonging to a local unprivileged user to gain re-ordered access to the descriptor table. (CVE-2008-1669, Important) * on AMD64 architectures, the possibility of a kernel crash was discovered by testing the Linux kernel process-trace ability. This could allow a local unprivileged user to cause a denial of service (kernel crash). (CVE-2008-1615, Important) * the absence of a protection mechanism when attempting to access a critical section of code, as well as a race condition, have been found in the Linux kernel file system event notifier, dnotify. This could allow a local unprivileged user to get inconsistent data, or to send arbitrary signals to arbitrary system processes.

    descriptionSome vulnerabilities were discovered and corrected in the Linux 2.6 kernel : Memory leak in the ipip6_rcv function in net/ipv6/sit.c in the Linux kernel before 2.6.25.3 allows remote attackers to cause a denial of service (memory consumption) via network traffic to a Simple Internet Transition (SIT) tunnel interface, related to the pskb_may_pull and kfree_skb functions, and management of an skb reference count. (CVE-2008-2136) The utimensat system call (sys_utimensat) in Linux kernel 2.6.22 and other versions before 2.6.25.3 does not check file permissions when certain UTIME_NOW and UTIME_OMIT combinations are used, which allows local users to modify file times of arbitrary files, possibly leading to a denial of service. (CVE-2008-2148) Integer overflow in the dccp_feat_change function in net/dccp/feat.c in the Datagram Congestion Control Protocol (DCCP) subsystem in the Linux kernel 2.6.18, and 2.6.17 through 2.6.20, allows local users to gain privileges via an invalid feature length, which leads to a heap-based buffer overflow. (CVE-2008-2358) The pppol2tp_recvmsg function in drivers/net/pppol2tp.c in the Linux kernel 2.6 before 2.6.26-rc6 allows remote attackers to cause a denial of service (kernel heap memory corruption and system crash) and possibly have unspecified other impact via a crafted PPPOL2TP packet that results in a large value for a certain length variable. (CVE-2008-2750) Linux kernel 2.6.18, and possibly other versions, when running on AMD64 architectures, allows local users to cause a denial of service (crash) via certain ptrace calls. (CVE-2008-1615) Integer overflow in the sctp_getsockopt_local_addrs_old function in net/sctp/socket.c in the Stream Control Transmission Protocol (sctp) functionality in the Linux kernel before 2.6.25.9 allows local users to cause a denial of service (resource consumption and system outage) via vectors involving a large addr_num field in an sctp_getaddrs_old data structure. (CVE-2008-2826) Race condition in the directory notification subsystem (dnotify) in Linux kernel 2.6.x before 2.6.24.6, and 2.6.25 before 2.6.25.1, allows local users to cause a denial of service (OOPS) and possibly gain privileges via unspecified vectors. (CVE-2008-1375) The bdx_ioctl_priv function in the tehuti driver (tehuti.c) in Linux kernel 2.6.x before 2.6.25.1 does not properly check certain information related to register size, which has unspecified impact and local attack vectors, probably related to reading or writing kernel memory. (CVE-2008-1675) Linux kernel before 2.6.25.2 does not apply a certain protection mechanism for fcntl functionality, which allows local users to (1) execute code in parallel or (2) exploit a race condition to obtain re-ordered access to the descriptor table. (CVE-2008-1669) Additionaly, a number of fixes has been included for the rtc driver, Arima W651DI audio chipset, unionfs, as well as Tomoyolinux has been updated to 1.6.3, UDF 2.50 support was added, and a few things more.

(CVE-2008-2372) - The asn1 implementation in (a) the Linux kernel, as used in the cifs and ip_nat_snmp_basic modules does not properly validate length values during decoding of ASN.1 BER data, which allows remote attackers to cause a denial of service (crash) or execute arbitrary code via (1) a length greater than the working buffer, which can lead to an unspecified overflow; (2) an oid length of zero, which can lead to an off-by-one error; or (3) an indefinite length for a primitive encoding. (CVE-2008-1673) - Various tty / serial devices did not check functionpointers for NULL before calling them, leading to potential crashes or code execution. The devices affected are usually only accessible by the root user though. (CVE-2008-2812) - A missing permission check in mount changing was added which could have been used by local attackers to change the mountdirectory. (CVE-2008-2931) Additionally a very large number of bugs was fixed. Details can be found in the RPM changelog of the included packages. OCFS2 has been upgraded to the 1.4.1 release : - Endian fixes - Use slab caches for DLM objects - Export DLM state info to debugfs - Avoid ENOSPC in rare conditions when free inodes are reserved by other nodes - Error handling fix in ocfs2_start_walk_page_trans() - Cleanup lockres printing - Allow merging of extents - Fix to allow changing permissions of symlinks - Merged local fixes upstream (no code change)

    titleSuSE 10 Security Update : Linux kernel (ZYPP Patch Number 5473)
  • NASL familyScientific Linux Local Security Checks
    NASL idSL_20080507_KERNEL_ON_SL3_X.NASL
    descriptionThese updated packages fix the following security issues : - the absence of a protection mechanism when attempting to access a critical section of code has been found in the Linux kernel open file descriptors control mechanism, fcntl. This could allow a local unprivileged user to simultaneously execute code, which would otherwise be protected against parallel execution. As well, a race condition when handling locks in the Linux kernel fcntl functionality, may have allowed a process belonging to a local unprivileged user to gain re-ordered access to the descriptor table. (CVE-2008-1669, Important) - the absence of a protection mechanism when attempting to access a critical section of code, as well as a race condition, have been found in the Linux kernel file system event notifier, dnotify. This could allow a local unprivileged user to get inconsistent data, or to send arbitrary signals to arbitrary system processes. (CVE-2008-1375, Important) - when accessing kernel memory locations, certain Linux kernel drivers registering a fault handler did not perform required range checks. A local unprivileged user could use this flaw to gain read or write access to arbitrary kernel memory, or possibly cause a kernel crash. (CVE-2008-0007, Important) - a flaw was found when performing asynchronous input or output operations on a FIFO special file. A local unprivileged user could use this flaw to cause a kernel panic. (CVE-2007-5001, Important) - a flaw was found in the way core dump files were created. If a local user could get a root-owned process to dump a core file into a directory, which the user has write access to, they could gain read access to that core file. This could potentially grant unauthorized access to sensitive information. (CVE-2007-6206, Moderate) - a buffer overflow was found in the Linux kernel ISDN subsystem. A local unprivileged user could use this flaw to cause a denial of service. (CVE-2007-6151, Moderate) - a race condition found in the mincore system core could allow a local user to cause a denial of service (system hang). (CVE-2006-4814, Moderate) - it was discovered that the Linux kernel handled string operations in the opposite way to the GNU Compiler Collection (GCC). This could allow a local unprivileged user to cause memory corruption. (CVE-2008-1367, Low) As well, these updated packages fix the following bugs : - a bug, which caused long delays when unmounting mounts containing a large number of unused dentries, has been resolved. - in the previous kernel packages, the kernel was unable to handle certain floating point instructions on Itanium(R) architectures. - on certain Intel CPUs, the Translation Lookaside Buffer (TLB) was not flushed correctly, which caused machine check errors.

(CVE-2008-1669, Important) * a possible hypervisor panic was found in the Linux kernel. A privileged user of a fully virtualized guest could initiate a stress-test File Transfer Protocol (FTP) transfer between the guest and the hypervisor, possibly leading to hypervisor panic. (CVE-2008-1619, Important) * the absence of a protection mechanism when attempting to access a critical section of code, as well as a race condition, have been found in the Linux kernel file system event notifier, dnotify. This could allow a local unprivileged user to get inconsistent data, or to send arbitrary signals to arbitrary system processes. (CVE-2008-1375, Important) Red Hat would like to thank Nick Piggin for responsibly disclosing the following issue : * when accessing kernel memory locations, certain Linux kernel drivers registering a fault handler did not perform required range checks. A local unprivileged user could use this flaw to gain read or write access to arbitrary kernel memory, or possibly cause a kernel crash. (CVE-2008-0007, Important) * the absence of sanity-checks was found in the hypervisor block backend driver, when running 32-bit paravirtualized guests on a 64-bit host. The number of blocks to be processed per one request from guest to host, or vice-versa, was not checked for its maximum value, which could have allowed a local privileged user of the guest operating system to cause a denial of service.

    descriptionThe CIFS filesystem in the Linux kernel before 2.6.22, when Unix extension support is enabled, does not honor the umask of a process, which allows local users to gain privileges. (CVE-2007-3740) The drm/i915 component in the Linux kernel before 2.6.22.2, when used with i965G and later chipsets, allows local users with access to an X11 session and Direct Rendering Manager (DRM) to write to arbitrary memory locations and gain privileges via a crafted batchbuffer. (CVE-2007-3851) The (1) hugetlb_vmtruncate_list and (2) hugetlb_vmtruncate functions in fs/hugetlbfs/inode.c in the Linux kernel before 2.6.19-rc4 perform certain prio_tree calculations using HPAGE_SIZE instead of PAGE_SIZE units, which allows local users to cause a denial of service (panic) via unspecified vectors. (CVE-2007-4133) The IA32 system call emulation functionality in Linux kernel 2.4.x and 2.6.x before 2.6.22.7, when running on the x86_64 architecture, does not zero extend the eax register after the 32bit entry path to ptrace is used, which might allow local users to gain privileges by triggering an out-of-bounds access to the system call table using the %RAX register. This vulnerability is now being fixed in the Xen kernel too. (CVE-2007-4573) Integer underflow in the ieee80211_rx function in net/ieee80211/ieee80211_rx.c in the Linux kernel 2.6.x before 2.6.23 allows remote attackers to cause a denial of service (crash) via a crafted SKB length value in a runt IEEE 802.11 frame when the IEEE80211_STYPE_QOS_DATA flag is set, aka an off-by-two error. (CVE-2007-4997) The disconnect method in the Philips USB Webcam (pwc) driver in Linux kernel 2.6.x before 2.6.22.6 relies on user space to close the device, which allows user-assisted local attackers to cause a denial of service (USB subsystem hang and CPU consumption in khubd) by not closing the device after the disconnect is invoked. NOTE: this rarely crosses privilege boundaries, unless the attacker can convince the victim to unplug the affected device. (CVE-2007-5093) A race condition in the directory notification subsystem (dnotify) in Linux kernel 2.6.x before 2.6.24.6, and 2.6.25 before 2.6.25.1, allows local users to cause a denial of service (OOPS) and possibly gain privileges via unspecified vectors.
