 Mandriva Linux Security Advisory                         MDVSA-2009:328
 http://www.mandriva.com/security/
 _______________________________________________________________________

 Package : ntp
 Date    : December 8, 2009
 Affected: 2008.0, 2009.0, 2009.1, 2010.0, Corporate 3.0, Corporate 4.0,
           Enterprise Server 5.0, Multi Network Firewall 2.0
 _______________________________________________________________________

 Problem Description:

 A vulnerability has been found and corrected in ntp:
 
 Robin Park and Dmitri Vinokurov discovered a flaw in the way ntpd
 handled certain malformed NTP packets. ntpd logged information about
 all such packets and replied with an NTP packet that was treated as
 malformed when received by another ntpd. A remote attacker could use
 this flaw to create an NTP packet reply loop between two ntpd servers
 via a malformed packet with a spoofed source IP address and port,
 causing ntpd on those servers to use excessive amounts of CPU time
 and fill disk space with log messages (CVE-2009-3563).
 
 This update provides a solution to this vulnerability.
