========================================================================== 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
