A security vulnerability with the server side support for "Local Drive Redirection" has been discovered (bug 7087). In 4.8.0 and earlier versions, it was possible for a local user to mount file systems outside their designated area, allowing for a local attacker to gain elevated privileges on the system. ThinLinc 4.8.1 has been released to correct this problem. Please note the new release also includes a 4.8.1 client, but it is without changes and identical to 4.8.0. No client update is needed.
