3. Description:

 

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

Users of rdesktop should upgrade to this updated package, which contains a

backported patch to resolve this issue.
