Mandriva Linux Security Advisory MDVSA-2013:059
http://www.mandriva.com/en/support/security/
_______________________________________________________________________

Package : dhcp
Date : April 8, 2013
Affected: Business Server 1.0
_______________________________________________________________________

Problem Description:

A security issue was identified and fixed in ISC DHCP:

libdns in ISC DHCP 4.2.x before 4.2.5-P1 allows remote name servers to
cause a denial of service (memory consumption) via vectors involving
a regular expression, as demonstrated by a memory-exhaustion attack
against a machine running a dhcpd process, a related issue to
CVE-2013-2266 (CVE-2013-2494).

The updated packages have upgraded to the 4.2.5-P1 version which is
not vulnerable to this issue
