[SECURITY] [DSA 1968-2] New pdns-recursor packages fix cache poisoning

Description

- ------------------------------------------------------------------------ Debian Security Advisory DSA-1968-2 security@debian.org http://www.debian.org/security/ Florian Weimer January 28, 2010 http://www.debian.org/security/faq - ------------------------------------------------------------------------ Package : pdns-recursor Vulnerability : DNS cache poisoning Problem type : remote Debian-specific: no CVE Id(s) : CVE-2009-4010 It was discovered that pdns-recursor, the PowerDNS recursive name server, contains a cache poisoning vulnerability which may allow attackers to trick the server into serving incorrect DNS data (CVE-2009-4010). This DSA provides a security update for the old stable distribution (etch), similar to the previous update in DSA-1968-1. (Note that the etch version of pdns-recursor was not vulnerable to CVE-2009-4009.) Extra care should be applied when installing this update. It is an etch backport of the lenny version of the package (3.1.7 with security fixes 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 version 3.1.4+v3.1.7-0+etch1. We recommend that you upgrade your pdns-recursor package.
