Summary
Red Hat Security Advisory: rdesktop security and bug fix update
Notes
Topic
Updated rdesktop packages that fix a security issue and a bug are now
available for Red Hat Enterprise Linux 4.
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 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)
Additionally, the following bug was fixed:
A missing command line option caused rdesktop to fail when using the krdc
remote desktop utility. Using krdc to connect to a terminal server resulted
in errors such as the following:
The version of rdesktop you are using ([version]) is too old:
rdesktop [version] or greater is required. A working patch for rdesktop
[version] can be found in KDE CVS.
In this updated package, krdc successfully connects to terminal servers.
Users of rdesktop should upgrade to these updated packages, which contain a
backported patches to resolve these issues.
