    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.
