Debian Security Advisory DSA-1971-1 security@debian.org
http://www.debian.org/security/ Giuseppe Iuculano
January 15, 2010 http://www.debian.org/security/faq
- ------------------------------------------------------------------------

Package : libthai
Vulnerability : integer overflow
Problem type : local (remote)
Debian-specific: no
CVE Id : CVE-2009-4012


Tim Starling discovered that libthai, a set of Thai language support routines,
is vulnerable of integer/heap overflow.
This vulnerability could allow an attacker to run arbitrary code by sending a very
long string.


For the oldstable distribution (etch), this problem has been fixed in
version 0.1.6-1+etch1.

For the stable distribution (lenny), this problem has been fixed in
version 0.1.9-4+lenny1.

For the testing distribution (squeeze), and the unstable distribution (sid),
this problem will be fixed soon.


We recommend that you upgrade your libthai package.

Upgrade instructions
- --------------------

wget url
will fetch the file for you
dpkg -i file.deb
will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
will update the internal database
apt-get upgrade
will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
