t1lib vulnerability
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.10
- Ubuntu 10.04 LTS
Summary:
t1lib could be made to crash or run programs as your login if it opened a
specially crafted font file.
Software Description:
- t1lib: Type 1 font rasterizer library - runtime
Details:
Jonathan Brossard discovered that t1lib did not correctly handle certain
malformed font files. If a user were tricked into using a specially crafted
font file, a remote attacker could cause t1lib to crash or possibly execute
arbitrary code with user privileges.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 11.10:
libt1-5 5.1.2-3ubuntu0.11.10.1
Ubuntu 11.04:
libt1-5 5.1.2-3ubuntu0.11.04.1

Ubuntu 10.04 LTS:

After a standard system update you need to restart your session to make
all the necessary changes.
