SYMPTOMS

In Windows Server 2008 and in Windows Vista, the LCMapString function may return incorrect mapping results for some languages.

Because of this issue, Exchange Server 2007 may enter an infinite loop when certain users connect to their mailboxes. Eventually, this behavior may consume all disk space, and the mail server may stop responding.

CAUSE

The LCMapString function is used to pass a locale, an input string, and a string length. If the string length parameter is specified, the input string cannot be null-terminated.

If the locale uses double compression, the system checks the next character to verify this double compression during the conversion. However, the system does not check whether the double-compressed locale exceeds the specified string length. If the locale string is null-terminated, no problem occurs. However, if the locale string ends on a page boundary, the system may crash.

RESOLUTION
