Excel is main focus of this month’s security patches from Microsoft.
It’s a familiar story, so Microsoft recycles their stock phrases from similar security lapses in the past.
A ‘specially crafted’ document can cause a ‘memory corruption’ in Office. The July 2017 patches fix not one, but two separate design errors in Office.
All supported versions of Excel need the updates, including Office for Mac 2011 & 2016.
- Excel 2016 (32 & 64-bit editions)
- Excel 2013 Service Pack 1 (32 & 64-bit editions)
- Excel 2013 RT Service Pack 1
- Excel 2010 SP2 (32 & 64-bit editions)
- Excel 2007 SP3
- Excel Viewer 2007 Service Pack 3
