Ubuntu Security Notice USN-1416-1
April 04, 2012
tiff vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.10
- Ubuntu 10.04 LTS
- Ubuntu 8.04 LTS
Summary:
The TIFF library could be made to crash or run programs as your login if it
opened a specially crafted file.
Software Description:
- tiff: Tag Image File Format (TIFF) library
Details:
Alexander Gavrun discovered that the TIFF library incorrectly allocated
space for a tile. If a user or automated system were tricked into opening a
specially crafted TIFF image, a remote attacker could execute arbitrary
code with user privileges, or crash the application, leading to a denial of
service. (CVE-2012-1173)
It was discovered that the tiffdump utility incorrectly handled directory
data structures with many directory entries. If a user or automated system
were tricked into opening a specially crafted TIFF image, a remote attacker
could crash the application, leading to a denial of service, or possibly
execute arbitrary code with user privileges. This issue only applied to
Ubuntu 8.04 LTS, Ubuntu 10.04 LTS, Ubuntu 10.10 and Ubuntu 11.04.
(CVE-2010-4665)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 11.10:
libtiff4 3.9.5-1ubuntu1.1
Ubuntu 11.04:
libtiff4 3.9.4-5ubuntu6.1
Ubuntu 10.10:
libtiff4 3.9.4-2ubuntu0.5
Ubuntu 10.04 LTS:
libtiff4 3.9.2-2ubuntu0.8
Ubuntu 8.04 LTS:
libtiff4 3.8.2-7ubuntu3.10
In general, a standard system update will make all the necessary changes.
