"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.

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).
