Ubuntu 10.04 LTS / 12.04 LTS / 14.04 LTS / 14.10 : unzip vulnerability (USN-2489-1)

Medium Nessus Plugin ID 81162


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


Michal Zalewski 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.
