It’s Microsoft Patch Tuesday February 2017! Well, not your regular Patch Tuesday. Patch Tuesday, or Update Tuesday, refers to the day each month when Microsoft releases security patches for its software. Microsoft normally issues the security bulletins and updates on the second Tuesday of each month. This month, however, Microsoft delayed its normal Patch Tuesday update until March 2017.
In today’s update, Microsoft released 1 security bulletin. The bulletin received a Critical rating. The patched vulnerability could have allowed remote code execution:
Microsoft Security Bulletin MS17-005 – Critical
Security Update for Adobe Flash Player (4010250)
According to Microsoft’s Security Bulletin Severity Rating System, Critical means:
A vulnerability whose exploitation could allow code execution without user interaction. These scenarios include self-propagating malware (e.g. network worms), or unavoidable common use scenarios where code execution occurs without warnings or prompts. This could mean browsing to a web page or opening email.
Microsoft recommends that customers apply Critical updates immediately.
