Debian DSA-1702-1 : ntp - interpretation conflict

Medium Nessus Plugin ID 35365

Synopsis

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

Description

It has been discovered that NTP, an implementation of the Network Time Protocol, does not properly check the result of an OpenSSL function for verifying cryptographic signatures, which may ultimately lead to the acceptance of unauthenticated time information. (Note that cryptographic authentication of time servers is often not enabled in the first place.)

Solution

Upgrade the ntp package.

For the stable distribution (etch), this problem has been fixed in version 4.2.2.p4+dfsg-2etch1.
