This could allow an attacker to cause the product to operate on unauthorized files. This is going to have an impact on integrity. CVE summarizes:

Samba before 2.2.0 allows local attackers to overwrite arbitrary files via a symlink attack using (1) a printer queue query, (2) the more command in smbclient, or (3) the mput command in smbclient.

The weakness was disclosed 07/02/2001 by Marcus Meissner with Caldera as confirmed advisory (CERT.org). The advisory is shared for download at kb.cert.org. This vulnerability is traded as CVE-2001-0406. The exploitability is told to be easy. The attack needs to be approached locally. The exploitation doesn't require any form of authentication. Technical details are unknown but a public exploit is available.

The exploit is shared for download at securityfocus.com. It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 14885 (Debian DSA-048-3 : samba), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks and running in the context l.

Upgrading eliminates this vulnerability. A possible mitigation has been published even before and not after the disclosure of the vulnerability.
