A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 10.10
- Ubuntu 10.04 LTS
Summary:
The TIFF library could be made to run programs as your login if it opened a
specially crafted file.
Software Description:
- tiff: TIFF manipulation and conversion tools
Details:
It was discovered that the TIFF library incorrectly handled certain JPEG
data. 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.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 10.10:
libtiff4 3.9.4-2ubuntu0.4
Ubuntu 10.04 LTS:
libtiff4 3.9.2-2ubuntu0.7
After a standard system update you need to restart your session to make
all the necessary changes.
