USN-2472-1: unzip vulnerabilities

Releases

• Ubuntu 14.10
• Ubuntu 14.04 ESM
• Ubuntu 12.04
• Ubuntu 10.04

Packages

• unzip - De-archiver for .zip files

Details

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

• unzip - 6.0-12ubuntu1.1

Ubuntu 14.04

• unzip - 6.0-9ubuntu1.1

Ubuntu 12.04

• unzip - 6.0-4ubuntu2.1

Ubuntu 10.04

• unzip - 6.0-1ubuntu0.1

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