|
|
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 ">=net-analyzer/wireshark-1.0.0"</code>
|
|
</resolution>
