USN11-1 : libgd2 vulnerabilities

Vulnerability Assessment Summary
libgd2 vulnerabilities

Detailed Explanation for this Vulnerability Assessment

Summary :

These remote packages are missing security patches :
- libgd-tools
- libgd2
- libgd2-dev
- libgd2-noxpm
- libgd2-noxpm-dev
- libgd2-xpm
- libgd2-xpm-dev


Description :

Several buffer overflows have been discovered in libgd's PNG handling
functions.

If a possible hacker tricked a user into loading a malicious PNG image, they
could leverage this into executing arbitrary code in the context of
the user opening image. Most importantly, this library is commonly
used in PHP. One possible target would be a PHP driven photo website
that lets users upload images. Therefore this vulnerability might lead
to privilege escalation to a web server's rights.

Solution :

Upgrade to :
- libgd-tools-2.0.23-2ubuntu0.1 (Ubuntu 4.10)
- libgd2-2.0.23-2ubuntu0.1 (Ubuntu 4.10)
- libgd2-dev-2.0.23-2ubuntu0.1 (Ubuntu 4.10)
- libgd2-noxpm-2.0.23-2ubuntu0.1 (Ubuntu 4.10)
- libgd2-noxpm-dev-2.0.23-2ubuntu0.1 (Ubuntu 4.10)
- libgd2-xpm-2.0.23-2ubuntu0.1 (Ubuntu 4.10)
- libgd2-xpm-dev-2.0.23-2ubuntu0.1 (Ubuntu 4.10)
