high Nessus Plugin ID 29263
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Debian host is missing a security-related update.

Description

Several local and remote vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or the execution of arbitrary code. The Common Vulnerabilities and Exposures project identifies the following problems :

This is an update to DSA 1428-1 which omitted a reference to CVE-2007-5904.

- CVE-2007-3104 Eric Sandeen provided a backport of Tejun Heo's fix for a local denial of service vulnerability in sysfs. Under memory pressure, a dentry structure maybe reclaimed resulting in a bad pointer dereference causing an oops during a readdir.

- CVE-2007-4997 Chris Evans discovered an issue with certain drivers that make use of the Linux kernel's ieee80211 layer. A remote user could generate a malicious 802.11 frame that could result in a denial of service (crash). The ipw2100 driver is known to be affected by this issue, while the ipw2200 is believed not to be.

- CVE-2007-5500 Scott James Remnant diagnosed a coding error in the implementation of ptrace which could be used by a local user to cause the kernel to enter an infinite loop.

- CVE-2007-5904 Przemyslaw Wegrzyn discovered an issue in the CIFS filesystem that could allow a malicious server to cause a denial of service (crash) by overflowing a buffer.

These problems have been fixed in the stable distribution in version 2.6.18.dfsg.1-13etch5.

The following matrix lists additional packages that were rebuilt for compatibility with or to take advantage of this update :

Debian 4.0 (etch) fai-kernels 1.17+etch.13etch5 user-mode-linux 2.6.18-1um-2etch.13etch5

Solution

Upgrade the kernel package immediately and reboot the machine. If you have built a custom kernel from the kernel source package, you will need to rebuild to take advantage of these fixes.
