Microsoft has recently become aware of a potential Excel SYLK file security vulnerability. When symbolic link (SYLK) files containing macros are opened in Excel 2000, users do not receive the usual macro warning dialog box. These macros could potentially delete files or perform other malicious acts on a computer. You could encounter this problem by opening an SYLK file that contains an Excel macro sheet that is attached to an e-mail message or islinked to from a Web site. This patch corrects the SYLK file vulnerability by displaying the macro warning dialog box whenever you open an SYLK file containing macros.
