Ubuntu 10.04 LTS / 12.04 LTS / 14.04 LTS / 14.10 : elfutils vulnerability (USN-2482-1)

Medium Nessus Plugin ID 80945

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

Alexander Cherepanov discovered that libelf1 incorrectly handled certain filesystem paths while extracting ar archives. An attacker could use this flaw to perform a directory traversal attack on the root directory if the process extracting the ar archive has write access to the root directory.

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 libelf1 package.
