Synopsis

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

Description

A flaw was found in how NTP checked the return value of signature verification. A remote attacker could use this to bypass certificate validation by using a malformed SSL/TLS signature (CVE-2009-0021).

The updated packages have been patched to prevent this issue.

Solution

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