<description>
<p>
acroread contains two errors in the handling of UUEncoded filenames.
First, it fails to check the length of a filename before copying it
into a fixed size buffer and, secondly, it fails to check for the
backtick shell metacharacter in the filename before executing a command
with a shell.
</p>
</description>
<impact type="normal">
<p>
By enticing a user to open a PDF with a specially crafted filename, an
attacker could execute arbitrary code or programs with the permissions
of the user running acroread.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time. All users are encouraged to
upgrade to the latest available version of acroread.
</p>
</workaround>
<resolution>
<p>
All acroread users should upgrade to the latest version:
</p>
<code>
# emerge sync
# emerge -pv &quot;&gt;=app-text/acroread-5.09&quot;
# emerge &quot;&gt;=app-text/acroread-5.09&quot;</code>
</resolution>
