The IA32 system call emulation functionality in arch/x86/ia32/ia32entry.S in the Linux kernel before 2.6.36-rc4-git2 on the x86_64 platform does not zero extend the %eax register after the 32-bit entry path to ptrace is used, which allows local users to gain privileges by triggering an out-of-bounds access to the system call table using the %rax register. NOTE: this vulnerability exists because of a CVE-2007-4573 regression.

This update of the openSUSE 11.3 kernel fixes two local root exploits, various other security issues and some bugs.

Following security issues are fixed by this update: CVE-2010-3301:
Mismatch between 32bit and 64bit register usage in the system call entry path could be used by local attackers to gain root privileges.
This problem only affects x86_64 kernels.

CVE-2010-3081: Incorrect buffer handling in the biarch-compat buffer handling could be used by local attackers to gain root privileges.
This problem affects foremost x86_64, or potentially other biarch platforms, like PowerPC and S390x.

CVE-2010-3084: A buffer overflow in the ETHTOOL_GRXCLSRLALL code could be used to crash the kernel or potentially execute code.

CVE-2010-2955: A kernel information leak via the WEXT ioctl was fixed.

CVE-2010-2960: The keyctl_session_to_parent function in security/keys/keyctl.c in the Linux kernel expects that a certain parent session keyring exists, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a KEYCTL_SESSION_TO_PARENT argument to the keyctl function.

CVE-2010-3080: A double free in an alsa error path was fixed, which could lead to kernel crashes.

CVE-2010-3079: Fixed a ftrace NULL pointer dereference problem which could lead to kernel crashes.

CVE-2010-3298: Fixed a kernel information leak in the net/usb/hso driver.

CVE-2010-3296: Fixed a kernel information leak in the cxgb3 driver.

CVE-2010-3297: Fixed a kernel information leak in the net/eql driver.

From Red Hat Security Advisory 2010:0704 :

Updated kernel packages that fix one security issue are now available for Red Hat Enterprise Linux 5.

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

A vulnerability was discovered and corrected in the Linux 2.6 kernel :

The compat_alloc_user_space functions in include/asm/compat.h files in the Linux kernel before 2.6.36-rc4-git2 on 64-bit platforms do not properly allocate the userspace memory required for the 32-bit compatibility layer, which allows local users to gain privileges by leveraging the ability of the compat_mc_getsockopt function (aka the MCAST_MSFILTER getsockopt support) to control a certain length value, related to a stack pointer underflow issue, as exploited in the wild in September 2010. (CVE-2010-3081)

The IA32 system call emulation functionality in arch/x86/ia32/ia32entry.S in the Linux kernel before 2.6.36-rc4-git2 on the x86_64 platform does not zero extend the %eax register after the 32-bit entry path to ptrace is used, which allows local users to gain privileges by triggering an out-of-bounds access to the system call table using the %rax register. NOTE: this vulnerability exists because of a CVE-2007-4573 regression. (CVE-2010-3301)

Integer overflow in the ext4_ext_get_blocks function in fs/ext4/extents.c in the Linux kernel before 2.6.34 allows local users to cause a denial of service (BUG and system crash) via a write operation on the last block of a large file, followed by a sync operation. (CVE-2010-3015)

Additionally, the kernel has been updated to the stable version 2.6.31.14. A timeout bug in bnx2 has been fixed. Muting and unmuting on VT1812/VT2002P now should work correctly. A fix for ACL decoding on NFS was added. Rebooting on Dell Precision WorkStation T7400 was corrected. Read balancing with RAID0 and RAID1 on drives larger then 2TB was also fixed. A more detailed description is available in the package changelog and related tickets.

Updated kernel packages that fix one security issue are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having important 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 kernel packages contain the Linux kernel, the core of any Linux operating system.

This update fixes the following security issue :

* The compat_alloc_user_space() function in the Linux kernel 32/64-bit compatibility layer implementation was missing sanity checks. This function could be abused in other areas of the Linux kernel if its length argument can be controlled from user-space. On 64-bit systems, a local, unprivileged user could use this flaw to escalate their privileges. (CVE-2010-3081, Important)

Red Hat would like to thank Ben Hawkes for reporting this issue.

Red Hat is aware that a public exploit for this issue is available.
