=========================================================== Ubuntu Security Notice USN-289-1 June 08, 2006 tiff vulnerabilities CVE-2006-2193, CVE-2006-2656 =========================================================== 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: libtiff-tools 3.6.1-5ubuntu0.5 Ubuntu 5.10: libtiff-tools 3.7.3-1ubuntu1.4 Ubuntu 6.06 LTS: libtiff-tools 3.7.4-1ubuntu3.1 In general, a standard system upgrade is sufficient to effect the necessary changes. Details follow: A buffer overflow has been found in the tiff2pdf utility. By tricking an user into processing a specially crafted TIF file with tiff2pdf, this could potentially be exploited to execute arbitrary code with the privileges of the user. (CVE-2006-2193) A. Alejandro Hernández discovered a buffer overflow in the tiffsplit utility. By calling tiffsplit with specially crafted long arguments, an user can execute arbitrary code. If tiffsplit is used in e. g. a web-based frontend or similar automated system, this could lead to remote arbitary code execution with the privileges of that system. (In normal interactive command line usage this is not a vulnerability.) (CVE-2006-2656)
