| Descripción: | Description:
The remote host is missing updates announced in
advisory RHSA-2007:1104.
The kernel packages contain the Linux kernel, the core of any Linux
operating system.
These updated packages fix the following security issues:
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file attributes, and outdated file size and timestamp information were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.
All users are advised to upgrade to these updated packages, which resolve
these issues.
