Mandriva Linux Security Advisory MDVSA-2011:182
http://www.mandriva.com/security/
_______________________________________________________________________

Package : dhcp
Date : December 8, 2011
Affected: 2010.1, 2011., Enterprise Server 5.0
_______________________________________________________________________

Problem Description:

A vulnerability has been discovered and corrected in dhcp:

dhcpd in ISC DHCP 4.x before 4.2.3-P1 and 4.1-ESV before 4.1-ESV-R4
does not properly handle regular expressions in dhcpd.conf, which
allows remote attackers to cause a denial of service (daemon crash)
via a crafted request packet (CVE-2011-4539).

The updated packages have been patched to correct this issue.
