Microsoft Patch Tuesday August 2017
When Microsoft changed its update process a few months ago, we were initially no longer able to quickly produce our usual assessment of Microsoft's patches. Finally, I think we have a way to get at least some of it back, and this is our first take on it. Please let me know if I should change anything. I know a few people wrote scripts to parse the table. I would recommend that you use Microsoft's own API to do so in the future. The layout of the table may change and screen-scraping is never a good idea.
What do the fields mean:
- Description: Microsoft's description of the flaw
- MSFT Severity: The highest severity Microsoft assigned to the flaw. Sometimes, Microsoft assigns different severities to different versions of the product affected by the flaw.
- CVE: CVE Number
- Disclosed/Exploited: Has the vulnerability been publicly disclosed or exploited in the wild prior to the release of the patch
- Exploitablity: How likley is it, that this vulnerability will be exploited. (old: oldest supported version of the sooftware, current: current software version)
- Client Severity: The severity we (ISC) assigned to this vulnerability for clients (Desktops)
- Server Severtiy: The severity we (ISC) assigned to this vulnerability to servers (servers run software like IIS and are more exposed to the internet)
Expect a few updates as I am refining the table. Use our contact form for feedback.
