Ubuntu 6.06 LTS / 6.10 / 7.04 : tar vulnerability (USN-506-1)

medium Nessus Plugin ID 28110

Synopsis

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

Description

Dmitry V. Levin discovered that tar did not correctly detect the '..' file path element when unpacking archives. If a user or an automated system were tricked into unpacking a specially crafted tar file, arbitrary files could be overwritten with user privileges.

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 tar package.
