A vulnerability was reported in R-Viewer. A remote user can cause arbitrary code to be executed on the target user's system. A local user can view the contents of sensitive files.|
A remote user can create a specially crafted RDZ file that, when loaded by the target user with the R-Viewer application, will execute the first file in the archive. The code will run with the privileges of the target user.
The system uses predictable temporary directories that contain unencrypted copies of the contents of the encrypted files. A local user can view the contents the files.

RemoteDocs R-Viewer is a secure document viewer used by remotedocs.com.
There exists a design flaw in RemoteDocs R-Viewer where code can be executed
upon opening the RDZ file without any knowlege or warning to the user.
Additionally, temporary files are not properly removed of disk exposing the
The problem is due to a design flaw in the R-Viewer application. It is
possible to replace the normal encrypted RDZ file with a specially
crafted RDZ file. The first file in this archive will be executed with
current user privledges by the R-Viewer application based strictly on file
To further compound this issue it may be possible for an attacker to gain
other sensitive information from the R-Viewer application through easily
predictable temporary directories that don't appear to expire content
regularily. Included inside of these temorary directories are the unecnrypted
copies of the documents the R-Viewer application has opened in the past.
