 Mandriva Linux Security Advisory                         MDVSA-2015:003
 http://www.mandriva.com/en/support/security/
 _______________________________________________________________________

 Package : ntp
 Date    : January 5, 2015
 Affected: Business Server 1.0
 _______________________________________________________________________

 Problem Description:

 Updated ntp packages fix security vulnerabilities:
 
 If no authentication key is defined in the ntp.conf file, a
 cryptographically-weak default key is generated (CVE-2014-9293).
 
 ntp-keygen before 4.2.7p230 uses a non-cryptographic random number
 generator with a weak seed to generate symmetric keys (CVE-2014-9294).
 
 A remote unauthenticated attacker may craft special packets that
 trigger buffer overflows in the ntpd functions crypto_recv() (when
 using autokey authentication), ctl_putdata(), and configure(). The
 resulting buffer overflows may be exploited to allow arbitrary
 malicious code to be executed with the privilege of the ntpd process
 (CVE-2014-9295).
 
 A section of code in ntpd handling a rare error is missing a return
 statement, therefore processing did not stop when the error was
 encountered. This situation may be exploitable by an attacker
 (CVE-2014-9296).
 
 The ntp package has been patched to fix these issues.
