Ubuntu 6.06 LTS / 7.10 : tar vulnerability (USN-709-1)

High Nessus Plugin ID 36397


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


Dmitry V. Levin discovered a buffer overflow in tar. If a user or automated system were tricked into opening a specially crafted tar file, an attacker could crash tar or possibly execute arbitrary code with the privileges of the user invoking the program.

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.


Update the affected tar package.
