** DISPUTED ** Guidance Software EnCase allows user-assisted remote attackers to cause a denial of service via (1) a corrupted Microsoft Exchange database which triggers an application crash when many options are selected; (2) a corrupted NTFS filesystem which causes the application to report \memory allocation errors;\ or (3) deeply nested directories which trigger an application crash during an Expand All action. NOTE: the vendor disputes the significance of these vectors because the user can select fewer options there is no operational impact or the user can do less expansion.
