This issue presents itself when the browser handles a large entry in the 'history.dat' file. An attacker may trigger this issue by enticing a user to visit a malicious website and by supplying excessive data to be stored in the affected file. This may cause a denial-of-service condition. **UPDATE: Proof-of-concept exploit code has been published. The author of the code attributes the crash to a buffer-overflow condition. Symantec has not reproduced the alleged flaw.
