RHEL 4 : kernel (RHSA-2007:1104)

medium Nessus Plugin ID 29774

Synopsis

The remote Red Hat host is missing one or more security updates for kernel.

Description

The remote Redhat Enterprise Linux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2007:1104 advisory.

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* when running the ls -la command on an NFSv4 mount point, incorrect file attributes, and outdated file size and timestamp information were returned.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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL kernel package based on the guidance in RHSA-2007:1104.
