-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- CONECTIVA LINUX SECURITY ANNOUNCEMENT - -------------------------------------------------------------------------- PACKAGE : libtiff3 SUMMARY : Fixes for libtiff vulnerabilities DATE : 2004-11-08 11:19:00 ID : CLA-2004:888 RELEVANT 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.
