LessTif is a clone of OSF/Motif, which is a standard user
interface toolkit available on Unix and Linux. OpenMotif also provides
a free version of the Motif toolkit for open source applications.
Chris Gilbert discovered potentially exploitable buffer overflow
cases in libXpm that weren't fixed in previous libXpm security
<impact type="normal">
A carefully-crafted XPM file could crash applications making use
of the OpenMotif or LessTif toolkits, potentially allowing the
execution of arbitrary code with the privileges of the user running the
There is no known workaround at this time.
All OpenMotif users should upgrade to an unaffected version:
# emerge --sync
# emerge --ask --oneshot --verbose x11-libs/openmotif</code>
All LessTif users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=x11-libs/lesstif-0.94.0-r2&quot;</code>
