USN-2472-1: unzip vulnerabilities

14 January 2015

unzip could be made to crash or run programs if it opened a specially crafted file.



  • unzip - De-archiver for .zip files


Wolfgang Ettlinger 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.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 14.10
Ubuntu 14.04
Ubuntu 12.04
Ubuntu 10.04

In general, a standard system update will make all the necessary changes.
