Debian Security Advisory DSA-2566-1 [email protected]
http://www.debian.org/security/ Nico Golde
October 25, 2012 http://www.debian.org/security/faq

Package : exim4
Vulnerability : heap-based buffer overflow
Problem type : remote
Debian-specific: no
CVE ID : CVE-2012-5671

It was discovered that Exim, a mail transport agent, is not properly
handling the decoding of DNS records for DKIM. Specifically, crafted
records can yield to a heap-based buffer overflow. An attacker can
exploit this flaw to execute arbitrary code.

For the stable distribution (squeeze), this problem has been fixed in
version 4.72-6+squeeze3.

For the testing distribution (wheezy), this problem has been fixed in
version 4.80-5.1.

For the unstable distribution (sid), this problem has been fixed in
version 4.80-5.1.

We recommend that you upgrade your exim4 packages.
