Description Tomas Hoger 2010-06-03 10:26:15 EDT
iDefense reported to us a libtiff flaw discovered by Dan Rosenberg. Quoting description from iDefense advisory draft: Remote exploitation of a stack buffer overflow vulnerability in version 3.9.2 of LibTIFF, as included in various vendors' operating system distributions, could allow an attacker to execute arbitrary code with the privileges of the current user. ... This vulnerability is due to insufficient bounds checking when copying data into a stack allocated buffer. During the processing of a certain EXIF tag a fixed sized stack buffer is used as a destination location for a memory copy. This memory copy can cause the bounds of a stack buffer to be overflown and this condition may lead to arbitrary code execution.
