RHSA-2007:1104: Important: kernel security and bug fix update

The kernel packages contain the Linux kernel, the core of any Linuxoperating system. These updated packages fix the following security issues:A flaw was found in the handling of IEEE 802.11 frames, which affectedseveral wireless LAN modules. In certain situations, a remote attackercould trigger this flaw by sending a malicious packet over a wirelessnetwork, causing a denial of service (kernel crash).(CVE-2007-4997, Important)A memory leak was found in the Red Hat Content Accelerator kernel patch.A local user could use this flaw to cause a denial of service (memoryexhaustion). (CVE-2007-5494, Important)Additionally, the following bugs were fixed: when running the "ls -la" command on an NFSv4 mount point, incorrect file attributes, and outdated file size and timestamp information werereturned. As well, symbolic links may have been displayed as actual files. a bug which caused the cmirror write path to appear deadlocked after a successful recovery, which may have caused syncing to hang, has beenresolved. a kernel panic which occurred when manually configuring LCS interfaces on the IBM S/390 has been resolved. when running a 32-bit binary on a 64-bit system, it was possible to mmap page at address 0 without flag MAPFIXED set. This has beenresolved in these updated packages. the Non-Maskable Interrupt (NMI) Watchdog did not increment the NMI interrupt counter in "/proc/interrupts" on systems running an AMD OpteronCPU. This caused systems running NMI Watchdog to restart at regularintervals. a bug which caused the diskdump utility to run very slowly on devices using Fusion MPT has been resolved.All users are advised to upgrade to these updated packages, which resolvethese issues.
