Technical Description

Debian has released updated packages to correct a vulnerability identified in Pam_ldap. This flaw is due to an error when a pam_ldap client attempts to authenticate against an LDAP server that omits the optional "error" value from the "PasswordPolicyResponseValue", which could be exploited by remote attackers to bypass the authentication procedure and gain access to a vulnerable system. For additional information, see : FrSIRT/ADV-2005-1520
