<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>
