Excel patch results in bad math

* Patches from Microsoft, Cisco, Ubuntu, others * Hackers launch massive IFRAME attack * Trend Micro hit by massive Web hack, and other interesting reading

For those that rely on Excel to supplement their math skills, watch out. One of last week’s security updates for the spreadsheet application caused a math bug. The flawed calculations should be obvious as all zeroes will be returned. Microsoft does have a workaround. And Cisco is out with a second patch in as many weeks, this time fixing a flaw in its CiscoWorks Internetwork Performance Monitor.

Buggy Microsoft Excel patch causes bad math

If you installed one of those Excel security patches issued by Microsoft earlier this week, you may want to double-check your math. That’s because a bug in the recent MS08-014 patch is causing Excel to return zeroes instead of the correct number when certain types of macros are run within the program. IDG News Service, 03/14/08.
