Debian Security Advisory DSA-1968-1 [email protected]
http://www.debian.org/security/ Florian Weimer

Package : pdns-recursor
Vulnerability : several
Problem type : remote
Debian-specific: no
CVE Id(s) : CVE-2009-4009 CVE-2009-4010
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.
