|Gentoo Linux Security Advisory
Title: pam_ldap: Authentication bypass vulnerability (GLSA 200508-22)
Date: August 31, 2005
pam_ldap contains a vulnerability that may allow a remote attacker to gain system access.
pam_ldap is a Pluggable Authentication Module which allows authentication against LDAP directories.
Vulnerable: < 180
Unaffected: >= 180
Architectures: All supported architectures
When a pam_ldap client attempts to authenticate against an LDAP server that omits the optional error value from the PasswordPolicyResponseValue, the authentication attempt will always succeed.
A remote attacker may exploit this vulnerability to bypass the LDAP authentication mechanism, gaining access to the system possibly with elevated privileges.
There is no known workaround at this time.
All pam_ldap users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-auth/pam_ldap-180"
