USN25-1 : libgd2 vulnerability |
||
libgd2 vulnerability 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 : CVE-2004-0990 described several more buffer overflows which had been discovered in libgd2's PNG handling functions. However, it was acertaind that the update from USN-11-1 was not sufficient to prevent every possible attack, so another update is required. 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-2.0.23-2ubuntu0.2 (Ubuntu 4.10) - libgd2-2.0.23-2ubuntu0.2 (Ubuntu 4.10) - libgd2-dev-2.0.23-2ubuntu0.2 (Ubuntu 4.10) - libgd2-noxpm-2.0.23-2ubuntu0.2 (Ubuntu 4.10) - libgd2-noxpm-dev-2.0.23-2ubuntu0.2 (Ubuntu 4.10) - libgd2-xpm-2.0.23-2ubuntu0.2 (Ubuntu 4.10) - libgd2-xpm-dev-2.0.23-2ubuntu0.2 (Ubuntu 4.10) Network Security Threat Level: High Networks Security ID: Vulnerability Assessment Copyright: Ubuntu Security Notice (C) 2005 Canonical, Inc. / NASL script (C) 2005 Michel Arboi |
