=========================================================== Ubuntu Security Notice USN-298-1 June 13, 2006 libgd2 vulnerability CVE-2006-2906 =========================================================== A security issue affects the following Ubuntu releases: Ubuntu 5.04 Ubuntu 5.10 Ubuntu 6.06 LTS This advisory also applies to the corresponding versions of Kubuntu, Edubuntu, and Xubuntu. The problem can be corrected by upgrading your system to the following package versions: Ubuntu 5.04: libgd2-noxpm 2.0.33-1.1ubuntu1.5.04 libgd2-xpm 2.0.33-1.1ubuntu1.5.04 Ubuntu 5.10: libgd2-noxpm 2.0.33-1.1ubuntu1.5.10 libgd2-xpm 2.0.33-1.1ubuntu1.5.10 Ubuntu 6.06 LTS: libgd2-noxpm 2.0.33-2ubuntu5.1 libgd2-xpm 2.0.33-2ubuntu5.1 After a standard system upgrade you need to reboot your computer to effect the necessary changes. Details follow: Xavier Roche discovered that libgd's function for reading GIF image data did not sufficiently verify its validity. Specially crafted GIF images could cause an infinite loop which used up all available CPU resources. Since libgd is often used in PHP and Perl web applications, this could lead to a remote Denial of Service vulnerability.
