Ubuntu Security Notice USN-1315-1
20th December, 2011
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.10
- Ubuntu 10.04 LTS
JasPer could be made to crash or run programs as your login if it opened a specially crafted file.
- jasper - Library for manipulating JPEG-2000 files
Jonathan Foote discovered that JasPer incorrectly handled certain malformed
JPEG-2000 image files. If a user were tricked into opening a specially
crafted JPEG-2000 image file, a remote attacker could cause JasPer to crash
or possibly execute arbitrary code with user privileges.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 11.10:
- libjasper1 1.900.1-7ubuntu18.104.22.168
- Ubuntu 11.04:
- libjasper1 1.900.1-7ubuntu2.11.04.1
- Ubuntu 10.10:
- libjasper1 1.900.1-7ubuntu0.10.10.1
- Ubuntu 10.04 LTS:
- libjasper1 1.900.1-7ubuntu0.10.04.1
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system update will make all the necessary changes.
