Symantec On-Demand Agent (SODA) and Symantec On-Demand Protection
(SODP) provide a Virtual Desktop environment to secure Web-based
applications and services. Files created while in the virtual desktop
are encrypted as they are saved to a hard drive or removable media, if
that option is enabled in the policy configuration. Symantec is aware
of a method which could potentially be used to defeat the encryption
on these files.

Symantec is aware of a method which can potentially be used to decrypt
files which were encrypted by the Symantec On-Demand Virtual Desktop.
An attacker who successfully used this method to decrypt files would
have access to the data in the files. The level of risk associated
with a successful attack is highly dependent on the content of the
encrypted files.

versions of Symantec On-Demand listed in the table above, and have
