Symantec Norton AntiVirus may hang or crash when the Auto-Protect module scans certain files.


Symantec Norton AntiVirus is an anti-virus product for desktop and enterprise use. The Norton AntiVirus "Auto-Protect" module provides automatic file scanning and detection of viruses, Trojans, and worms. However, the Auto-Protect module may hang when scanning certain file types.


A user may be able to cause the system to crash or hang by introducing a certain file type to the system. The user may introduce the file by downloading it, copying it, or receiving it in electronic mail, for example. Electronic mail and similar file introduction vectors may allow a remote attacker to exploit this flaw with a minimum of local user interaction.
