Summary
Red Hat Security Advisory: rdesktop security update

Notes

Topic
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.
Details
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.
