Package: nsd
Version: 2.3.7-1.1
Severity: grave
Tags: security
Dear NSD users and maintainers,
We have released version 3.2.2. of NSD. This is *critical* bugfix
release. One of the bugs is a one-byte buffer overflow that allows a
carefully crafted exploit to take down your name-server. It is highly
unlikely that the one-byte-off issue can lead to other (system) exploits.
The bug affects all version of NSD 2.0.0 to 3.2.1. Whether the bug can
be exploited to depends on various aspects of the OS and is therefore
distribution and compiler dependent.
For more information:
http://www.nlnetlabs.nl/publications/NSD_vulnerability_announcement.html
We strongly recommend you to update your systems to the latest version.
If you have reasons for not running the latest version of NSD, we
strongly advise you to at least apply the patch that resolves the
critical bug.
The source and patches are available at our website:

RELNOTES:
BUG FIXES:
- - Off-by-one buffer overflow fix while processing the QUESTION section.
- - Return BADVERS when NSD does not implement the VERSION level of the
request, instead of 0x1<FORMERR>.
- - Bugfix #234.
- - Bugfix #235.
- - Reset 'error occurred' after notifying an error occurred at the $TTL
or $ORIGIN directive (Otherwise, the whole zone is skipped because the
error is reset after reading the SOA).
- - Minor bugfixes.
