Debian Security Advisory DSA-1795 security@debian.org
http://www.debian.org/security/ Devin Carraway
May 07, 2009 http://www.debian.org/security/faq
- - ------------------------------------------------------------------------
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.
