FKIE_CVE-2006-5170
Vulnerability from fkie_nvd - Published: 2006-10-10 04:06 - Updated: 2026-06-16 22:30
Severity
Summary
pam_ldap in nss_ldap on Red Hat Enterprise Linux 4, Fedora Core 3 and earlier, and possibly other distributions does not return an error condition when an LDAP directory server responds with a PasswordPolicyResponse control response, which causes the pam_authenticate function to return a success code even if authentication has failed, as originally reported for xscreensaver.
