Debian Lenny DSA-1968-1 Critical: Pdns-Recursor Buffer Overflow

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

A buffer overflow can be exploited to crash the daemon, or potentially
execute arbitrary code (CVE-2009-4009).

A cache poisoning vulnerability may allow attackers to trick the
server into serving incorrect DNS data (CVE-2009-4010).

For the old stable 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.
