Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 14.10 - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS - Ubuntu 10.04 LTS

Details:

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.

Update instructions:

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

Ubuntu 14.10:
unzip 6.0-12ubuntu1.2

Ubuntu 14.04 LTS:
unzip 6.0-9ubuntu1.2

Ubuntu 12.04 LTS:
unzip 6.0-4ubuntu2.2

Ubuntu 10.04 LTS:
unzip 6.0-1ubuntu0.2

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