 Mandriva Linux Security Advisory                         MDVSA-2015:202

 Package : ntp
 Date    : April 10, 2015
 Affected: Business Server 1.0, Business Server 2.0

 Problem Description:

 Multiple vulnerabilities has been found and corrected in ntp:
 The symmetric-key feature in the receive function in ntp_proto.c
 in ntpd in NTP before 4.2.8p2 requires a correct MAC only if the MAC
 field has a nonzero length, which makes it easier for man-in-the-middle
 attackers to spoof packets by omitting the MAC (CVE-2015-1798).
 The symmetric-key feature in the receive function in ntp_proto.c
 in ntpd in NTP before 4.2.8p2 performs state-variable updates
 upon receiving certain invalid packets, which makes it easier
 for man-in-the-middle attackers to cause a denial of service
 (synchronization loss) by spoofing the source IP address of a peer
 The updated packages provides a solution for these security issues.
