The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-200806-04
(rdesktop: Multiple vulnerabilities)
An anonymous researcher reported multiple vulnerabilities in rdesktop
via iDefense Labs:
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
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).
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
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.
There is no known workaround at this time.
