I clicked on the Lock icon on the bottom portion, entered my password (administrator account) and still I find it greyed out. What should I do that will allow me to change these settings?
Please NOTE: If you already have Sophos installed, you do not need to download the new software manually.
Just modify your update server settings to the new servers which are listed under your Operating Systems download page and Sophos will automatically upgrade for you.
While researching inter-process communication on Mac OS X, I found a small security issue with Sophos Anti-Virus for Mac: any local user can remove arbitrary files on the system via the Update functionality of the product. I started by listing all Sophos processes on my Mac Book: All except GUI run as root and are unsandboxed! So if some user creates a symbolic link to some sensitive file owned by a privileged user, it will be deleted during the update procedure since the process doing deletion (unlinking) runs as and is not sandboxed.
Trustwave security advisory has proof-of-concept code that removes root-owned file via this vulnerability.
Unwanted and malicious programs that can be stealthily installed on the system or can force the user to download some dubious application or a plug-in for a browser without the user’s knowledge are well known to Doctor Web security researchers. In particular, among the SDK files, there is the configuration file that has a special section with the information regarding what applications should be downloaded.
