XADM: Access Violation Occurs While Processing Long DBCS BinHex Files (195894)

The information in this article applies to:

Microsoft Exchange Server 5.5

This article was previously published under Q195894

SYMPTOMS

An access violation error happens when processing long double-byte character set (DBCS) attachment files, which are encoded in BinHex format.

CAUSE

The current logic assumes that if a leading byte is found, the trailing byte must follow. However, the trailing byte is removed because of shrinking long attachment file names, and then the access violation happens.

RESOLUTION

To resolve this problem, obtain the latest service pack for Exchange Server version 5.5. For more information, please see the following article in the Microsoft Knowledge Base:
