Ubuntu 6.06 LTS / 8.04 LTS / 8.10 / 9.04 : linux, linux-source-2.6.15 vulnerability (USN-819-1)

high Nessus Plugin ID 40658
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 Ubuntu host is missing one or more security-related patches.

Description

Tavis Ormandy and Julien Tinnes discovered that Linux did not correctly initialize certain socket operation function pointers. A local attacker could exploit this to gain root privileges. By default, Ubuntu 8.04 and later with a non-zero /proc/sys/vm/mmap_min_addr setting were not vulnerable.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected packages.
