Symantec Norton AntiVirus may hang or crash when the Auto-Protect module SmartScan feature scans a renamed file on a network share.
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. The Auto-Protect module includes a feature called "SmartScan" which, as an alternative to scanning all file types, only scans specifically targeted file types and extensions. A flaw in the SmartScan feature is triggered when a file residing on a network share is renamed that may cause excessive CPU consumption and an eventual system hang or crash as a result.
A local authenticated user may be able to cause the system to crash or hang by renaming a file residing on a network share.
