pdns-recursor - potential code execution

It was discovered that pdns-recursor, the PowerDNS recursive name
server, contains several vulnerabilities:

• CVE-2009-4009
  A buffer overflow can be exploited to crash the daemon, or potentially
  execute arbitrary code.
• CVE-2009-4010
  A cache poisoning vulnerability may allow attackers to trick the
  server into serving incorrect DNS data.

For the oldstable distribution (etch), fixed packages will be
provided soon.

For the stable distribution (lenny), these problems have been fixed in
version 3.1.7-1+lenny1.

For the unstable distribution (sid), these problems have been fixed in
version 3.1.7.2-1.

We recommend that you upgrade your pdns-recursor package.
