Debian Security Advisory

DSA-1831-1 djbdns -- programming error

Date Reported:

13 Jul 2009

Affected Packages:

djbdns

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 518169.
In Mitre's CVE dictionary: CVE-2009-0858.

More information:

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.

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.

For the unstable distribution (sid), this problem has been fixed in version 1.05-5.

We recommend that you upgrade your djbdns package.

Fixed in:

Debian GNU/Linux 5.0 (lenny)
