Debian Security Advisory DSA-1795 security@debian.org

- ------------------------------------------------------------------------

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
will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
will update the internal database
apt-get upgrade
will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
