 Mandriva Linux Security Advisory                       MDVSA-2012:153-1

 _______________________________________________________________________

 Package : dhcp
 Date    : October 2, 2012
 Affected: 2011.
 _______________________________________________________________________

 Problem Description:

 A security issue was identified and fixed in dhcp:
 
 ISC DHCP 4.1.x before 4.1-ESV-R7 and 4.2.x before 4.2.4-P2 allows
 remote attackers to cause a denial of service (daemon crash)
 in opportunistic circumstances by establishing an IPv6 lease in
 an environment where the lease expiration time is later reduced
 (CVE-2012-3955).
 
 The updated packages have been patched to correct this issue.

 Update:

 Packages for Mandriva Linux 2011 is being provided.
 
 The updated packages have been upgraded to dhcp 4.2.4-P2 which is
 not vulnerable to this issue.
