USN-1587-1: libxml2 vulnerability
Ubuntu Security Notice USN-1587-1
27th September, 2012
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.04 LTS
- Ubuntu 8.04 LTS
Applications using libxml2 could be made to crash or run programs as your login if they opened a specially crafted file.
- libxml2 - GNOME XML library
Juri Aedla discovered that libxml2 incorrectly handled certain memory
operations. If a user or application linked against libxml2 were tricked
into opening a specially crafted XML file, an attacker could cause the
application to crash or possibly execute arbitrary code with the privileges
of the user invoking the program.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 12.04 LTS:
- libxml2 2.7.8.dfsg-5.1ubuntu4.2
- Ubuntu 11.10:
- libxml2 2.7.8.dfsg-4ubuntu0.4
- Ubuntu 11.04:
- libxml2 2.7.8.dfsg-2ubuntu0.5
- Ubuntu 10.04 LTS:
- libxml2 2.7.6.dfsg-1ubuntu1.6
- Ubuntu 8.04 LTS:
- libxml2 2.6.31.dfsg-2ubuntu1.10
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
After a standard system update you need to reboot your computer to make
all the necessary changes.
