medium Nessus Plugin ID 64810
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

Suleiman Souhlal, Salman Qazi, Aaron Durbin and Michael Davidson discovered a race condition in the Linux kernel's ptrace syscall. An unprivileged local attacker could exploit this flaw to run programs as an administrator.

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 linux-image-3.5-generic and / or linux-image-3.5-highbank packages.
