Ubuntu Security Notice USN-2190-1
1st May, 2014
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.04 LTS
- Ubuntu 13.10
- Ubuntu 12.10
JBIG-KIT could be made to crash or run programs if it processed a specially crafted image file.
- jbigkit - JBIG1 data compression library
Florian Weimer discovered that JBIG-KIT incorrectly handled certain
malformed images. If a user or automated system were tricked into
processing a specially crafted image, JBIG-KIT could be made to crash, or
possibly execute arbitrary code.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 14.04 LTS:
- libjbig0 2.0-2ubuntu4.1
- Ubuntu 13.10:
- libjbig0 2.0-2ubuntu22.214.171.124
- Ubuntu 12.10:
- libjbig0 2.0-2ubuntu126.96.36.199
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.
