March 2010 by Vigil@nce

A local attacker may forbid the access to users authenticated by LDAP.

- Severity: 1/4

- Provenance: user shell
- Means of attack: no proof of concept, no attack
- Ability of attacker: expert (4/4)
- Confidence: confirmed by the editor (5/5)
- Diffusion of the vulnerable configuration: high (3/3)
- Creation date: 01/03/2010

IMPACTED PRODUCTS

- IBM AIX

DESCRIPTION OF THE VULNERABILITY

The authentication of users can be managed by LDAP.

When AIX 5.3 Technology Level 11 Service Pack 2 with bos.rte.security 5.3.11.1 is installed, legitimate users cannot access to the system via LDAP.

IBM does not indicate if this behavior is created by a bug, of if it can be created by a local attacker.
