Package name kernel
Date December 21st, 2005
Advisory ID MDKSA-2005:235
Affected versions 2006.0
Synopsis Updated kernel packages fix numerous vulnerabilities

Problem Description

Multiple vulnerabilities in the Linux 2.6 kernel have been discovered and corrected in this update: A stack-based buffer overflow in the sendmsg function call in versions prior to allow local users to execute arbitrary code by calling sendmsg and modifying the message contents in another thread (CVE-2005-2490). The raw_sendmsg function in versions prior to allow local users to cause a DoS (change hardware state) or read from arbitrary memory via crafted input (CVE-2005-2492). The ipt_recent module in versions prior to 2.6.12 does not properly perform certain tests when the jiffies value is greater than LONG_MAX, which can cause ipt_recent netfilter rules to block too early (CVE-2005-2873). Multiple vulnerabilities in versions prior to allow local users to cause a DoS (oops from null dereference) via fput in a 32bit ioctl on 64-bit x86 systems or sockfd_put in the 32-bit routing_ioctl function on 64-bit systems (CVE-2005-3044). Versions 2.6.8 to 2.6.14-rc2 allow local users to cause a DoS (oops) via a userspace process that issues a USB Request Block (URB) to a USB device and terminates before the URB is finished, which leads to a stale pointer reference (CVE-2005-3055). drm.c in version 2.6.13 and earlier creates a debug file in sysfs with world-readable and world-writable permissions, allowing local users to enable DRM debugging and obtain sensitive information (CVE-2005-3179). The Orinoco driver in 2.6.13 and earlier does not properly clear memory from a previously used packet whose length is increased, allowing remote attackers to obtain sensitive information (CVE-2005-3180). Kernels 2.6.13 and earlier, when CONFIG_AUDITSYSCALL is enabled, use an incorrect function to free names_cache memory, preventing the memory from being tracked by AUDITSYSCALL code and leading to a memory leak (CVE-2005-3181). The VT implementation in version 2.6.12 allows local users to use certain IOCTLs on terminals of other users and gain privileges (CVE-2005-3257). A race condition in ip_vs_conn_flush in versions prior to 2.6.13, when running on SMP systems, allows local users to cause a DoS (null dereference) by causing a connection timer to expire while the connection table is being flushed before the appropriate lock is acquired (CVE-2005-3274). The provided packages are patched to fix these vulnerabilities. All users are encouraged to upgrade to these updated kernels.

To upgrade your kernel, view the kernel update instructions. Kernels cannot be upgraded via MandrakeUpdate.


Please verify the update prior to upgrading to ensure the integrity of the downloaded package. You can do this with the command :

                rpm --checksig package.rpm

You can get the GPG public key of the Mandriva Security Team to verify the GPG signature of each RPM.
