MDKSA-2005:235: kernel |

Check for the version of the kernel package Detailed Explanation for this Vulnerability Assessment The remote host is missing the patch for the advisory MDKSA-2005:235 (kernel). 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 2.6.13.1 permit 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 2.6.13.1 permit 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 2.6.13.2 permit 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 permit 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, permiting 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, permiting 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 permits local users to use certain IOCTLs on terminals of other users and gain rights (CVE-2005-3257). A race condition in ip_vs_conn_flush in versions prior to 2.6.13, when running on SMP systems, permits 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.
