Debian Security Advisory DSA 1203-1 [email protected]

Package : libpam-ldap
Vulnerability : programming error
Problem-Type : remote
Debian-specific: no
CVE ID : CVE-2006-5170
Debian Bug : 392984

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.
