Microsoft warns of Excel hyperlink bug
Second flaw to hit spreadsheet application in as many days
Hot on the heels of Microsoft’s warning of an unpatched flaw in Excel earlier this week, the firm’s Security Response Center is investigating reports of a second vulnerability affecting the spreadsheet application.
The company began investigating after the appearance of proof-of-concept PERL script claiming to demonstrate a vulnerability in Excel’s processing of long links, according to a posting on the Microsoft Security Response Center blog.
The flaw is actually a vulnerability in ‘hlink.dll’, a Windows component that handles operations involving hyperlinks.
