Details

USN-2553-1 fixed vulnerabilities in LibTIFF. One of the security fixes
caused a regression when saving certain TIFF files with a Predictor tag.
The problematic patch has been temporarily backed out until a more complete
fix is available.

We apologize for the inconvenience.

Original advisory details:

William Robinet discovered that LibTIFF incorrectly handled certain
malformed images. If a user or automated system were tricked into opening a
specially crafted image, a remote attacker could crash the application,
leading to a denial of service, or possibly execute arbitrary code with
user privileges. (CVE-2014-8127, CVE-2014-8128, CVE-2014-8129,
CVE-2014-8130)

Paris Zoumpouloglou discovered that LibTIFF incorrectly handled certain
malformed BMP images. If a user or automated system were tricked into
opening a specially crafted BMP image, a remote attacker could crash the
application, leading to a denial of service. (CVE-2014-9330)

Michal Zalewski discovered that LibTIFF incorrectly handled certain
malformed images. If a user or automated system were tricked into opening a
specially crafted image, a remote attacker could crash the application,
leading to a denial of service, or possibly execute arbitrary code with
user privileges. (CVE-2014-9655)
