Description

This security bulletin contains information about 1 security vulnerability.


1) Security restrictions bypass (CVE-ID: CVE-2013-1060)

The vulnerability allows a local user to execute arbitrary code.

A certain Ubuntu build procedure for perf, as distributed in the Linux kernel packages in Ubuntu 10.04 LTS, 12.04 LTS, 12.10, 13.04, and 13.10, sets the HOME environment variable to the ~buildd directory and consequently reads the system configuration file from the ~buildd directory, which allows local users to gain privileges by leveraging control over the buildd account.


Remediation

Install update from vendor's website.
