|
|
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 ">=net-misc/rdesktop-1.6.0"</code>
|
|
</resolution>
