Description:
Two vulnerabilities have been reported in NOD32, which can be exploited by malicious, local users to gain escalated privileges.

1) The NOD32 GUI (nod32.exe) runs with SYSTEM privileges when a scheduled on-demand scan is being run by the scheduler. This can be exploited to invoke cmd.exe with SYSTEM privileges when a scheduled scan is running.

The vulnerability has been confirmed in version 2.5 for WinNT/2k/XP/2003 (nod32krn.exe/nod32.exe 2.51.20.0). Other versions may also be affected.

2) The program doesn't drop its SYSTEM privileges before allowing a user to use the "Restore to..." feature to restore a quarantined file. This can be exploited to write a file to an arbitrary directory with SYSTEM privileges if a file with the given filename doesn't already exist.
