USN159-1 : unzip vulnerability

Vulnerability Assessment Summary
unzip vulnerability

Detailed Explanation for this Vulnerability Assessment

Summary :

The remote package "unzip" is missing a security patch.

Description :

If a ZIP archive contains binaries with the setuid and/or setgid bit
set, unzip preserved those bits when extracting the archive. This
could be exploited by tricking the administrator into unzipping an
archive with a setuid-root binary into a directory the attacker can
access. This permited the attacker to execute arbitrary commands with
root rights.

The updated version does not preserve setuid, setgid, and sticky bits
any more by default. The old behaviour can be explicitly requested now
by supplying the option '-K'.

Solution :

Upgrade to :
- unzip-5.51-2ubuntu1.1 (Ubuntu 5.04)

Network Security Threat Level: High
