Package : pdns-recursor
Vulnerability : DNS cache poisoning
Problem type : remote
CVE Id(s) : CVE-2009-4010

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

(etch), similar to the previous update in DSA-1968-1. (Note that the

applied). Major differences in internal domain name processing made
backporting just the security fix too difficult.
For the old stable distribution (etch), this problem has been fixed in
