Advisory Content (Page 1 of 3)[ 1 ] [ 2 ] [ 3 ]

Description:
A security issue has been reported in pam_ldap, which can be exploited by malicious people to bypass certain security restrictions.

The problem is caused due to an error when a pam_ldap client authenticates against an LDAP server that returns a passwordPolicyResponse control in a BindResponse without the optional "error" field.

Successful exploitation grants access without checking the authentication result.

The security issue has been reported in versions 169 through 179.
