SynopsisThe remote Mandriva Linux host is missing one or more security updates.
DescriptionUpdated 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.
SolutionUpdate the affected ntp, ntp-client and / or ntp-doc packages.
