DSA-143-1 krb5 -- integer overflow

Debian Security Advisory

DSA-143-1 krb5 -- integer overflow

Date Reported:

05 Aug 2002

Affected Packages:

krb5

Vulnerable:

Yes

Security database references:

In the Bugtraq database (at SecurityFocus): BugTraq ID 5356.
In Mitre's CVE dictionary: CVE-2002-0391.
CERT's vulnerabilities, advisories and incident notes: VU#192995.

More information:

An integer overflow bug has been discovered in the RPC library used by the Kerberos 5 administration system, which is derived from the SunRPC library. This bug could be exploited to gain unauthorized root access to a KDC host. It is believed that the attacker needs to be able to authenticate to the kadmin daemon for this attack to be successful. No exploits are known to exist yet.

This problem has been fixed in version 1.2.4-5woody1 for the current stable distribution (woody) and in version 1.2.5-2 for the unstable distribution (sid). Debian 2.2 (potato) is not affected since it doesn't contain krb5 packages.

We recommend that you upgrade your kerberos packages immediately.

Fixed in:

Debian GNU/Linux 3.0 (woody)
