<description>
<p>
Errors exist in:
</p>
<ul>
<li>
the X.509sat dissector because of an uninitialized variable and the
Roofnet dissector because a NULL pointer may be passed to the
g_vsnprintf() function (CVE-2008-1561).</li>
<li>
the LDAP dissector because a NULL pointer may be passed to the
ep_strdup_printf() function (CVE-2008-1562).</li>
<li>
the SCCP dissector because it does not reset a pointer once the packet
has been processed (CVE-2008-1563).</li>
</ul>
</description>
<impact type="normal">
<p>
A remote attacker could exploit these vulnerabilities by sending a
malformed packet or enticing a user to read a malformed packet trace
file, causing a Denial of Service.
</p>
</impact>
<workaround>
<p>
Disable the X.509sat, Roofnet, LDAP, and SCCP dissectors.
</p>
</workaround>
<resolution>
<p>
All Wireshark users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-analyzer/wireshark-1.0.0&quot;</code>
</resolution>
