tag_insight = "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.";
