Ubuntu Security Notice USN-3212-2
May 30, 2017
tiff regression
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
– Ubuntu 16.10
– Ubuntu 16.04 LTS
– Ubuntu 14.04 LTS
Summary:
USN-3212-1 caused a regression in LibTIFF.
Software Description:
– tiff: Tag Image File Format (TIFF) library
Details:
www.cert.hr/node/30535USN-3212-1 fixed vulnerabilities in LibTIFF. Unfortunately, some of the
security patches were misapplied, which caused a regression when processing
certain images. This update fixes the problem.
We apologize for the inconvenience.
Original advisory details:
It was 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.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 16.10:
libtiff-tools 4.0.6-2ubuntu0.2
libtiff5 4.0.6-2ubuntu0.2
Ubuntu 16.04 LTS:
libtiff-tools 4.0.6-1ubuntu0.2
libtiff5 4.0.6-1ubuntu0.2
Ubuntu 14.04 LTS:
libtiff-tools 4.0.3-7ubuntu0.7
libtiff5 4.0.3-7ubuntu0.7
In general, a standard system update will make all the necessary changes.
