Ubuntu 12.04 LTS / 14.04 LTS / 14.10 : unzip vulnerabilities (USN-2502-1)

High Nessus Plugin ID 81400


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


William Robinet discovered that unzip incorrectly handled certain malformed zip archives. If a user or automated system were tricked into processing a specially crafted zip archive, an attacker could possibly execute arbitrary code.

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 unzip package.
