dnsmasq - remote code execution

Several remote vulnerabilities have been discovered in the TFTP
component of dnsmasq. The Common Vulnerabilities and Exposures
project identifies the following problems:

• CVE-2009-2957
  A buffer overflow in TFTP processing may enable arbitrary code
  execution to attackers which are permitted to use the TFTP service.
• CVE-2009-2958
  Malicious TFTP clients may crash dnsmasq, leading to denial of
  service.

The old stable distribution is not affected by these problems.

For the stable distribution (lenny), these problems have been fixed in
version 2.45-1+lenny1.

For the unstable distribution (sid), these problems have been fixed in
version 2.50-1.

We recommend that you upgrade your dnsmasq packages.
