Ubuntu Security Notice USN-2553-2
April 01, 2015

tiff regression
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 14.10
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS

Summary:

USN-2553-1 introduced a regression in LibTIFF.

Software Description:
- tiff: Tag Image File Format (TIFF) library

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)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 14.10:
libtiff5 4.0.3-10ubuntu0.2

Ubuntu 14.04 LTS:
libtiff5 4.0.3-7ubuntu0.3

Ubuntu 12.04 LTS:
libtiff4 3.9.5-2ubuntu1.8

Ubuntu 10.04 LTS:
libtiff4 3.9.2-2ubuntu0.16

In general, a standard system update will make all the necessary changes.
