4) Description of Vulnerability

Secunia Research has discovered a security issue in Symantec Discovery,
which can be exploited by malicious, local users to gain escalated
privileges.

The problem is caused due to insecure default file permissions being
set on the "Discovery" directory. This can be exploited to gain
escalated privileges by placing malicious files or replacing e.g
certain DLL files in the directory.
