[GLSA-200612-19] pam_ldap: Authentication bypass vulnerability |
||
pam_ldap: Authentication bypass vulnerability Detailed Explanation for this Vulnerability Assessment 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.
