DESCRIPTION
libtiff[1] is a library for handling TIFF images.
wxGTK[2] is the GTK+2 port of the wxWidgets library, an open source
C++ GUI framework.
Several vulnerabilities were found in libtiff, which may also be in
wxGTK library, since it has a private copy of libtiff's source.
The fixed vulnerabilities are:
CAN-2004-0803[3]: Chris Evans encountered several problems in the RLE
(Run Length Encoding) decoders that could lead to an arbitrary code
execution vulnerability through a specially crafted image.
CAN-2004-0804[4]: Matthias Clasen encountered a division by zero
through an integer overflow that could lead to a denial of service
vulnerability which could be triggered by a specially crafted image.
CAN-2004-0886[5]: Dmitry V. Levin encountered several integer
overflows that caused malloc issues which could result in either
plain a crash or memory corruption.
SOLUTION
It is recommended that all wxgtk2 library users upgrade their
packages.
IMPORTANT: all applications linked against libff must be restarted
after the upgrade in order to close the vulnerabilities.
