... Microsoft user forums have been flooded with complaints of issues with Outlook following the company's recent release of its monthly Patch Tuesday update bundle. The software giant released four critical patches and eight others ranked 'important' in its bundle earlier this week. But one of the patches - MS15-115 - is creating unintended side effects for Outlook users. The patch was intended to address a flaw in Windows' handling of fonts, and prevent remote code execution if an attacker convinces a user to either open a malicious document or visit an untrusted webpage that contains embedded fonts.
