Miloslav Trmac from Red Hat discovered a buffer overflow in the
"readline()" function of texindex.c. The "readline()" function is
called by the texi2dvi and texindex commands.

<impact type="normal">
<p>
By enticing a user to open a specially crafted Texinfo file, an
attacker could execute arbitrary code with the rights of the user
running Texinfo.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All Texinfo users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=sys-apps/texinfo-4.8-r5&quot;</code>
</resolution>
