Debian DSA-1831-1 : djbdns - programming error

medium Nessus Plugin ID 44696

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

Matthew Dempsky discovered that Daniel J. Bernstein's djbdns, a Domain Name System server, does not constrain offsets in the required manner, which allows remote attackers with control over a third-party subdomain served by tinydns and axfrdns, to trigger DNS responses containing arbitrary records via crafted zone data for this subdomain.

Solution

Upgrade the djbdns package.

The old stable distribution (etch) does not contain djbdns.

For the stable distribution (lenny), this problem has been fixed in version 1.05-4+lenny1.
