Mandriva Linux Security Advisory : ntp (MDVSA-2015:003)

High Nessus Plugin ID 80384

New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 6.7

Synopsis

The remote Mandriva Linux host is missing one or more security updates.

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.

Solution

Update the affected ntp, ntp-client and / or ntp-doc packages.
