    Package        : ldns
    Vulnerability  : buffer overflow
    Problem type   : local (remote)
    Debian-specific: no
    CVE Id(s)      : CVE-2009-1086
    
    Stefan Kaltenbrunner discovered that ldns, a library and set of utilities
    to facilitate DNS programming, did not correctly implement a buffer
    boundary check in its RR DNS record parser.  This weakness could enable
    overflow of a heap buffer if a maliciously-crafted record is parsed,
    potentially allowing the execution of arbitrary code.  The scope of
    compromise will vary with the context in which ldns is used, and could
    present either a local or remote attack vector.
    
    The old stable distribution (etch) is not affected by this issue.
    
    For the stable distribution (lenny), this problem has been fixed in
    version 1.4.0-1+lenny1.
    
    For the unstable distribution (sid), this problem was fixed in
    version 1.5.1-1.
    
    We recommend that you upgrade your ldns packages.
    
    Upgrade instructions
    - --------------------
    
    wget url
            will fetch the file for you
    dpkg -i file.deb
