DESCRIPTION:
A security issue has been reported in OpenPAM, which can be exploited
by malicious, local users to gain escalated privileges.
The security issue is caused due to an input sanitisation error when
loading PAM services, which can be exploited to e.g. load malicious
libraries with root privileges via directory traversal attacks.
Note: Successful exploitation requires that an attacker can e.g. pass
a malicious server name to OpenPAM's "pam_start()" function (e.g. the
kcheckpass utility on FreeBSD).
The security issue is reported in OpenPAM Hydrangea. Other versions
may also be affected.
SOLUTION:
Restrict access to trusted users only.
