Created attachment 2167 [details] [SECURITY] Update libpng to 1.2.44 Several versions of libpng through 1.4.2 (and through 1.2.43 in the older series) contain a bug whereby progressive applications such as web browsers (or the rpng2 demo app included in libpng) could receive an extra row of image data beyond the height reported in the header, potentially leading to an out-of-bounds write to memory (depending on how the application is written) and the possibility of execution of an attacker's code with the privileges of the libpng user (including remote compromise in the case of a libpng-based browser visiting a hostile web site). This vulnerability has been assigned ID CVE-2010-1205 (via Mozilla). An additional memory-leak bug, involving images with malformed sCAL chunks, is also present; it could lead to an application crash (denial of service) when viewing such images.
