Heap-based buffer overflow in NOD32 2.5 with nod32.002 1.033 build 1127, with active scanning enabled, allows remote attackers to execute arbitrary code via an ARJ archive containing a file with a long filename.

The "restore to" selection in the "quarantine a file" capability of ESET NOD32 before 2.51.26 allows a restore to any directory that permits read access by the invoking user, which allows local users to create new files despite write-access directory permissions.

The GUI (nod32.exe) in NOD32 2.5 runs with SYSTEM privileges when the scheduler runs a scheduled on-demand scan, which allows local users to execute arbitrary code during a scheduled scan via unspecified attack vectors.
