PACKAGE : libtiff3
SUMMARY : Fixes for libtiff vulnerabilities
DATE : 2004-11-08 11:19:00

RELEASES : 9, 10

DESCRIPTION
libtiff[1] is a library for handling TIFF images.
This announcement fixes several integer overflow vulnerabilities that
were encountered in libtiff.
The fixed vulnerabilities are:
CAN-2004-0803: 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: 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: 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 libtiff users upgrade their packages.
IMPORTANT: all applications linked against libff must be restarted
after the upgrade in order to close the vulnerabilities.
