    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.
