  A local privilege escalation vulnerability has been identified in
  Photodex ProShow Producer v5.0.3310.
  
  Insecure file permissions on the executable file "scsiaccess.exe", which
  is used by the application service "ScsiAccess" under the SYSTEM
  account, may allow a less privileged user to gain access to SYSTEM
  privileges. A local attacker or compromised process is able to replace
  the original application binary with a malicious application which will
  be executed by a victim user or after a ScsiAccess service restart.
