RHBA-2010:0527 - Bug Fix Advisory

Topic

An updated autofs5 package that fixes a bug is now available.

Description

The autofs utility controls the operation of the automount daemon, which
automatically mounts, and then unmounts file systems after a period of
inactivity. File systems can include network file systems, CD-ROMs, diskettes,
and other media.

This updated autofs5 package fixes the following bug:

• as it is used quite often, the Network File System (NFS) mount module is

pre-opened and cached by the "parse_sun" module, so that it can be accessed by
other modules very quickly. However, especially with a high number of
simultaneously running threads, it was possible for a race condition to arise,
causing the automount5 daemon to terminate unexpectedly with a segmentation
fault. This error has been fixed, and automount5 should now work as expected.
(BZ#609088)

All users of autofs5 are advised to upgrade to this updated package, which
resolves this issue.
