[GLSA-200612-19] pam_ldap: Authentication bypass vulnerability Vulnerability Scan
Vulnerability Scan Summary
pam_ldap: Authentication bypass vulnerability
Detailed Explanation for this Vulnerability Test
The remote host is affected by the vulnerability described in GLSA-200612-19
(pam_ldap: Authentication bypass vulnerability)
Steve Rigler discovered that pam_ldap does not correctly handle
"PasswordPolicyResponse" control responses from an LDAP directory. This
causes the pam_authenticate() function to always succeed, even if the
previous authentication failed.
Impact
A locked user may exploit this vulnerability to bypass the LDAP
authentication mechanism, possibly gaining unauthorized access to the
system.
Workaround
There is no known workaround at this time.
