Debian Security Advisory

DSA-1203-1 libpam-ldap -- programming error

Date Reported:
02 Nov 2006
Affected Packages:
libpam-ldap
Vulnerable:
Yes
Security database references:
In the Debian bugtracking system: Bug 392984.
In Mitre's CVE dictionary: CVE-2006-5170.
More information:

Steve Rigler discovered that the PAM module for authentication against LDAP servers processes PasswordPolicyReponse control messages incorrectly, which might lead to an attacker being able to login into a suspended system account.

For the stable distribution (sarge) this problem has been fixed in version 178-1sarge3. Due to technical problems with the security buildd infrastructure this update lacks a build for the Sun Sparc architecture. It will be released as soon as the problems are resolved.

For the unstable distribution (sid) this problem has been fixed in version 180-1.2.

We recommend that you upgrade your libpam-ldap package.

Fixed in:

Debian GNU/Linux 3.1 (sarge)
