+ <synopsis>
+ Multiple Denial of Service vulnerabilities have been discovered in
+ Wireshark.

+ <background>
+ <p>
+ Wireshark is a network protocol analyzer with a graphical front-end.
+ </p>
+ </background>
+ <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 "&gt;=net-analyzer/wireshark-1.0.0"</code>
