Summary

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 vulnerability was 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)
Users of rdesktop should upgrade to these updated packages, which contain a backported patch to resolve this issue.
