Package : dhcp
Vulnerability : buffer overflow
Problem type : remote
Debian-specific: no
CVE Id(s) : CVE-2007-5365
Debian Bug : 446354

The patch used to correct the DHCP server buffer overflow in DSA-1388-1
was incomplete and did not adequately resolve the problem. This update
to the previous advisory makes available updated packages based on a
newer version of the patch.

For the stable distribution (etch), this problem has been fixed in
version 2.0pl5-19.5etch2

Updates to the old stable version (sarge) are pending.

We recommend that you upgrade your dhcp packages.
