Description

A flaw was found in the handling of IEEE 802.11 frames, which affected several wireless LAN modules. In certain situations, a remote attacker could trigger this flaw by sending a malicious packet over a wireless network, 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 (memory exhaustion). (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  • when running the 'ls -la' command on an NFSv4 mount point, incorrect file attributes, and outdated file size and timestamp information were returned. 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 been resolved.

  • 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 MAP_FIXED set. This has been resolved 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 Opteron CPU. This caused systems running NMI Watchdog to restart at regular intervals.

  • a bug which caused the diskdump utility to run very slowly on devices using Fusion MPT has been resolved.
