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.
