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.

"Updated ecryptfs-utils packages that fix several security issues are
now available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having
moderate 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.

eCryptfs is a stacked, cryptographic file system. It is transparent to
the underlying file system and provides per-file granularity. eCryptfs
is released as a Technology Preview for Red Hat Enterprise Linux 5 and
6.

The setuid mount.ecryptfs_private utility allows users to mount an
eCryptfs file system. This utility can only be run by users in the
'ecryptfs' group.

A race condition flaw was found in the way mount.ecryptfs_private
checked the permissions of a requested mount point when mounting an
encrypted file system. A local attacker could possibly use this flaw
to escalate their privileges by mounting over an arbitrary directory.
(CVE-2011-1831)

A race condition flaw in umount.ecryptfs_private could allow a local
attacker to unmount an arbitrary file system. (CVE-2011-1832)

It was found that mount.ecryptfs_private did not handle certain errors
correctly when updating the mtab (mounted file systems table) file,
allowing a local attacker to corrupt the mtab file and possibly
unmount an arbitrary file system. (CVE-2011-1834)

An insecure temporary file use flaw was found in the
ecryptfs-setup-private script. A local attacker could use this script
to insert their own key that will subsequently be used by a new user,
possibly giving the attacker access to the user's encrypted data if
existing file permissions allow access. (CVE-2011-1835)

A race condition flaw in mount.ecryptfs_private could allow a local
attacker to overwrite arbitrary files. (CVE-2011-1837)

A race condition flaw in the way temporary files were accessed in
mount.ecryptfs_private could allow a malicious, local user to make
arbitrary modifications to the mtab file. (CVE-2011-3145)

A race condition flaw was found in the way mount.ecryptfs_private
checked the permissions of the directory to mount. A local attacker
could use this flaw to mount (and then access) a directory they would
otherwise not have access to. Note: The fix for this issue is
incomplete until a kernel-space change is made. Future Red Hat
Enterprise Linux 5 and 6 kernel updates will correct this issue.
(CVE-2011-1833)

Red Hat would like to thank the Ubuntu Security Team for reporting
these issues. The Ubuntu Security Team acknowledges Vasiliy Kulikov of
Openwall and Dan Rosenberg as the original reporters of CVE-2011-1831,
CVE-2011-1832, and CVE-2011-1833; Dan Rosenberg and Marc Deslauriers
as the original reporters of CVE-2011-1834; Marc Deslauriers as the
original reporter of CVE-2011-1835; and Vasiliy Kulikov of Openwall as
the original reporter of CVE-2011-1837.

Users of ecryptfs-utils are advised to upgrade to these updated
packages, which contain backported patches to correct these issues."

"eCryptfs is a stacked, cryptographic file system. It is transparent to
the underlying file system and provides per-file granularity.

The setuid mount.ecryptfs_private utility allows users to mount an
eCryptfs file system. This utility can only be run by users in the
'ecryptfs' group.

A race condition flaw was found in the way mount.ecryptfs_private
checked the permissions of a requested mount point when mounting an
encrypted file system. A local attacker could possibly use this flaw
to escalate their privileges by mounting over an arbitrary directory.
(CVE-2011-1831)

A race condition flaw in umount.ecryptfs_private could allow a local
attacker to unmount an arbitrary file system. (CVE-2011-1832)

It was found that mount.ecryptfs_private did not handle certain errors
correctly when updating the mtab (mounted file systems table) file,
allowing a local attacker to corrupt the mtab file and possibly
unmount an arbitrary file system. (CVE-2011-1834)

An insecure temporary file use flaw was found in the
ecryptfs-setup-private script. A local attacker could use this script
to insert their own key that will subsequently be used by a new user,
possibly giving the attacker access to the user's encrypted data if
existing file permissions allow access. (CVE-2011-1835)

A race condition flaw in mount.ecryptfs_private could allow a local
attacker to overwrite arbitrary files. (CVE-2011-1837)

A race condition flaw in the way temporary files were accessed in
mount.ecryptfs_private could allow a malicious, local user to make
arbitrary modifications to the mtab file. (CVE-2011-3145)

A race condition flaw was found in the way mount.ecryptfs_private
checked the permissions of the directory to mount. A local attacker
could use this flaw to mount (and then access) a directory they would
otherwise not have access to. Note: The fix for this issue is
incomplete until a kernel-space change is made. Future Scientific
Linux 5 and 6 kernel updates will correct this issue. (CVE-2011-1833)

Users of ecryptfs-utils are advised to upgrade to these updated
packages, which contain backported patches to correct these issues."

    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

The generator was changed to use full 32bit randomness. (CVE-2011-3188) - Fernando Gont discovered that the IPv6 stack used predictable fragment identification numbers. A remote attacker could exploit this to exhaust network resources, leading to a denial of service. (CVE-2011-2699) - A NULL ptr dereference on mounting corrupt hfs filesystems was fixed which could be used by local attackers to crash the kernel. (CVE-2011-2203) - 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-2011-1833) - The Generic Receive Offload (GRO) implementation in the Linux kernel allowed remote attackers to cause a denial of service via crafted VLAN packets that are processed by the napi_reuse_skb function, leading to (1) a memory leak or (2) memory corruption, a different vulnerability than CVE-2011-1478. (CVE-2011-1576) - A name overflow in the hfs filesystem was fixed, where mounting a corrupted hfs filesystem could lead to a stack overflow and code execution in the kernel. This requires a local attacker to be able to mount hfs filesystems. (CVE-2011-4330) - A bug was found in the way headroom check was performed in udp6_ufo_fragment() function.

    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.

    descriptionThe skb_gro_header_slow function in include/linux/netdevice.h in the Linux kernel before 2.6.39.4, when Generic Receive Offload (GRO) is enabled, resets certain fields in incorrect situations, which allows remote attackers to cause a denial of service (system crash) via crafted network traffic. Race condition in the ecryptfs_mount function in fs/ecryptfs/main.c in the eCryptfs subsystem in the Linux kernel before 3.1 allows local users to bypass intended file permissions via a mount.ecryptfs_private mount with a mismatched uid. The (1) IPv4 and (2) IPv6 implementations in the Linux kernel before 3.1 use a modified MD4 algorithm to generate sequence numbers and Fragment Identification values, which makes it easier for remote attackers to cause a denial of service (disrupted networking) or hijack network sessions by predicting these values and sending crafted packets. Integer signedness error in the CIFSFindNext function in fs/cifs/cifssmb.c in the Linux kernel before 3.1 allows remote CIFS servers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a large length value in a response to a read request for a directory. The Performance Events subsystem in the Linux kernel before 3.1 does not properly handle event overflows associated with PERF_COUNT_SW_CPU_CLOCK events, which allows local users to cause a denial of service (system hang) via a crafted application.

    descriptionSeveral vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or privilege escalation. The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2009-4307 Nageswara R Sastry reported an issue in the ext4 filesystem. Local users with the privileges to mount a filesystem can cause a denial of service (BUG) by providing a s_log_groups_per_flex value greater than 31. - CVE-2011-1833 Vasiliy Kulikov of Openwall and Dan Rosenberg discovered an information leak in the eCryptfs filesystem. Local users were able to mount arbitrary directories. - CVE-2011-4347 Sasha Levin reported an issue in the device assignment functionality in KVM. Local users with permission to access /dev/kvm could assign unused pci devices to a guest and cause a denial of service (crash). - CVE-2012-0045 Stephan Barwolf reported an issue in KVM. Local users in a 32-bit guest running on a 64-bit system can crash the guest with a syscall instruction. - CVE-2012-1090 CAI Qian reported an issue in the CIFS filesystem. A reference count leak can occur during the lookup of special files, resulting in a denial of service (oops) on umount. - CVE-2012-1097 H. Peter Anvin reported an issue in the regset infrastructure. Local users can cause a denial of service (NULL pointer dereference) by triggering the write methods of readonly regsets.

    descriptionRyan Sweat discovered that the kernel incorrectly handled certain VLAN packets. On some systems, a remote attacker could send specially crafted traffic to crash the system, leading to a denial of service. (CVE-2011-1576) Vasiliy Kulikov and Dan Rosenberg discovered that ecryptfs did not correctly check the origin of mount points. A local attacker could exploit this to trick the system into unmounting arbitrary mount points, leading to a denial of service. (CVE-2011-1833) Vasiliy Kulikov discovered that taskstats did not enforce access restrictions. A local attacker could exploit this to read certain information, leading to a loss of privacy. (CVE-2011-2494) Vasiliy Kulikov discovered that /proc/PID/io did not enforce access restrictions. A local attacker could exploit this to read certain information, leading to a loss of privacy. (CVE-2011-2495) Dan Rosenberg discovered that the Bluetooth stack incorrectly handled certain L2CAP requests. If a system was using Bluetooth, a remote attacker could send specially crafted traffic to crash the system or gain root privileges. (CVE-2011-2497) It was discovered that the EXT4 filesystem contained multiple off-by-one flaws. A local attacker could exploit this to crash the system, leading to a denial of service. (CVE-2011-2695) Fernando Gont discovered that the IPv6 stack used predictable fragment identification numbers. A remote attacker could exploit this to exhaust network resources, leading to a denial of service. (CVE-2011-2699) Christian Ohm discovered that the perf command looks for configuration files in the current directory. If a privileged user were tricked into running perf in a directory containing a malicious configuration file, an attacker could run arbitrary commands and possibly gain privileges. (CVE-2011-2905) Time Warns discovered that long symlinks were incorrectly handled on Be filesystems. A local attacker could exploit this with a malformed Be filesystem and crash the system, leading to a denial of service. (CVE-2011-2928) Dan Kaminsky discovered that the kernel incorrectly handled random sequence number generation. An attacker could use this flaw to possibly predict sequence numbers and inject packets. (CVE-2011-3188) Darren Lavender discovered that the CIFS client incorrectly handled certain large values. A remote attacker with a malicious server could exploit this to crash the system or possibly execute arbitrary code as the root user. (CVE-2011-3191) Han-Wen Nienhuys reported a flaw in the FUSE kernel module. A local user who can mount a FUSE file system could cause a denial of service.
