+ <background>
+ <p>
+ rdesktop is an open source Remote Desktop Protocol (RDP) client.
+ </p>
+ </background>
+ <description>
+ <p>
+ An anonymous researcher reported multiple vulnerabilities in rdesktop
+ via iDefense Labs:
+ </p>
+ <ul>
+ <li>An integer underflow error exists in
+ the function iso_recv_msg() in the file iso.c which can be triggered
+ via a specially crafted RDP request, causing a heap-based buffer
+ overflow (CVE-2008-1801).</li>
+ <li>An input validation error exists in
+ the function process_redirect_pdu() in the file rdp.c which can be
+ triggered via a specially crafted RDP redirect request, causing a
+ BSS-based buffer overflow (CVE-2008-1802).</li>
+ <li>
+ An integer signedness error exists in the function xrealloc() in the
+ file rdesktop.c which can be be exploited to cause a heap-based buffer
+ overflow (CVE-2008-1803).</li>
+ </ul>
+ </description>
+ <impact type="normal">
+ <p>
+ An attacker could exploit these vulnerabilities by enticing a user to
+ connect to a malicious RDP server thereby allowing the attacker to
+ execute arbitrary code or cause a Denial of Service.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ There is no known workaround at this time.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All rdesktop users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose &quot;&gt;=net-misc/rdesktop-1.6.0&quot;</code>
+ </resolution>
