"Updated libtiff packages that fix various integer overflows are now
available.

The libtiff package contains a library of functions for manipulating
TIFF (Tagged Image File Format) image format files.

iDEFENSE has reported an integer overflow bug that affects libtiff. An
attacker who has the ability to trick a user into opening a malicious
TIFF file could cause the application linked to libtiff to crash or
possibly execute arbitrary code. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CVE-2004-1308
to this issue.

Dmitry V. Levin reported another integer overflow in the tiffdump
utility. An attacker who has the ability to trick a user into opening
a malicious TIFF file with tiffdump could possibly execute arbitrary
code. The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CVE-2004-1183 to this issue.

All users are advised to upgrade to these updated packages, which
contain backported fixes for these issues."
