Synopsis :

The remote Oracle Linux host is missing a security update.

Description :

From Red Hat Security Advisory 2011:0506 :

An updated rdesktop package that fixes one security issue is now
available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having
moderate security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from
the CVE link in the References section.

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.
