Debian Security Advisory

DSA-1388-3 dhcp -- buffer overflow

Date Reported:

29 Oct 2007

Affected Packages:

dhcp

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 446354.
In Mitre's CVE dictionary: CVE-2007-5365.

More information:

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 This update to the previous advisory makes updated packages based on a newer version of the patch available.

For completeness, please find below the original advisory:

It was discovered that dhcp, a DHCP server for automatic IP address assignment, didn't correctly allocate space for network replies. This could potentially allow a malicious DHCP client to execute arbitrary code upon the DHCP server.

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

For the unstable distribution (sid), this problem will be fixed shortly.

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

We recommend that you upgrade your dhcp packages.

Fixed in:

Debian GNU/Linux 3.1 (sarge)
