 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.
