Debian Security Advisory

DSA-801-1 ntp -- programming error

Date Reported:

05 Sep 2005

Affected Packages:

ntp

Vulnerable:

Yes

Security database references:

In Mitre's CVE dictionary: CVE-2005-2496.

More information:

SuSE developers discovered that ntp confuses the given group id with the group id of the given user when called with a group id on the commandline that is specified as a string and not as a numeric gid, which causes ntpd to run with different privileges than intended.

The old stable distribution (woody) is not affected by this problem.

For the stable distribution (sarge) this problem has been fixed in version 4.2.0a+stable-2sarge1.

The unstable distribution (sid) is not affected by this problem.

We recommend that you upgrade your ntp-server package.

Fixed in:

Debian GNU/Linux 3.1 (sarge)
