Synopsis

The remote Red Hat host is missing a security update for rdesktop.

Description

The remote Redhat Enterprise Linux 6 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2011:0506 advisory.

rdesktop is a client for the Remote Desktop Server (previously, Terminal Server) in Microsoft Windows. It uses the Remote Desktop Protocol (RDP) to remotely present a user's desktop.

A directory traversal flaw was found in the way rdesktop shared a local path with a remote server. If a user connects to a malicious server with rdesktop, the server could use this flaw to cause rdesktop to read and write to arbitrary, local files accessible to the user running rdesktop.
(CVE-2011-1595)

Red Hat would like to thank Cendio AB for reporting this issue. Cendio AB acknowledges an anonymous contributor working with the SecuriTeam Secure Disclosure program as the original reporter.

Users of rdesktop should upgrade to this updated package, which contains a backported patch to resolve this issue.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL rdesktop package based on the guidance in RHSA-2011:0506.
