Debian DSA-045-2 : ntpd - remote root exploit

critical Nessus Plugin ID 14882

Synopsis

The remote Debian host is missing a security-related update.

Description

Przemyslaw Frasunek <[email protected]> reported that ntp daemons such as that released with Debian GNU/Linux are vulnerable to a buffer overflow that can lead to a remote root exploit. A previous advisory (DSA-045-1) partially addressed this issue, but introduced a potential denial of service attack. This has been corrected for Debian 2.2 (potato) in ntp version 4.0.99g-2potato2.

Solution

Upgrade the affected ntpd package.
