RHBA-2013:1738 - fprintd bug fix update

Synopsis

fprintd bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated fprintd packages that fix one bug are now available for Red Hat Enterprise Linux 6.

Description

The fprintd packages contain a D-Bus service to access fingerprint readers.

This update fixes the following bug:

• When the Pluggable Authentication Module (PAM) configuration includes the pam_fprintd module, PAM uses the glib2 functions where the dlclose() function is executed to unload the glib2 libraries. However, this method is not designed for multi-threaded applications. When a PAM operation was made, Directory Server on Red Hat Enterprise Linux 6 terminated unexpectedly during the shutdown phase because it attempted to unload the glib2 destructor, which had been previously unloaded by the fprintd service. This update applies a patch to fix this bug so that fprintd no longer unloads glib2 when pam_fprintd closes. As a result, the glib2 libraries are unloaded when Directory Server is closed and therefore the server shuts down gracefully. (BZ#1003940)

Users of fprintd are advised to upgrade to these updated packages, which fix this bug.

Solution
