"From Red Hat Security Advisory 2008:0575 :

An updated rdesktop package that fixes a security issue is now
available for Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the
Red Hat Security Response Team.

rdesktop is an open source client for Microsoft Windows NT Terminal
Server and Microsoft Windows 2000 and 2003 Terminal Services, capable
of natively using the Remote Desktop Protocol (RDP) to present the
user's NT desktop. No additional server extensions are required.

An integer underflow and integer signedness issue were discovered in
the rdesktop. If an attacker could convince a victim to connect to a
malicious RDP server, the attacker could cause the victim's rdesktop
to crash or, possibly, execute an arbitrary code. (CVE-2008-1801,
CVE-2008-1803)

Users of rdesktop should upgrade to these updated packages, which
contain a backported patches to resolve these issues."
