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.
