am-utils is a collection of utilities for use with the Berkeley
Tavis Ormandy discovered that, when creating temporary files, the
'expn' utility does not check whether the file already exists.

All am-utils users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-fs/am-utils-6.1.5&quot;</code>
