Here are the top vendors by the count of vulnerabilities.
Advisories by Vendors
RedHat, SUSE and Amazon are among the top vendors which reported vulnerabilities in Linux based operating systems. While Oracle Linux is in 6th and Microsoft is at 9th Place with 13 advisories. The notion of Microsoft with most vulnerable products has changed over time where Open source has taken over top vendors with most vulnerabilities.
5 being the highest criticality, the below graph shows the average criticality per vendor which is sorted based on the number of advisories.

Count of SAID versus Average CVSS 3 score
As usual, most vulnerabilities can be exploited from remote which makes the remediation efforts even more important.
Advisories by Average CVSS Score
Common Vulnerability Scoring System – CVSS is a common industry standard to rate the severity of vulnerabilities. It ranges between 10 and 0 with 10 being the highest. Currently, CVSS standards are version 3.
Advisories by Solution
90% of vulnerabilities had a solution while 89.5% percent of vulnerabilities had a patch on the day the advisory was released.
The new feature in Software vulnerability Research and Software Vulnerability Management solutions helps our customers to prioritize and remediation based on the accurate threat landscape. There were a couple of vulnerabilities with a very high threat score. Google Chrome and Internet explorers were among the software with the highest threat score.

CVSS 3 Score
SAIDs with Low CVSS3 score >= 4.0: 25 (6.39%)
SAIDs with Mid CVSS3 range 4-7: 146 (37.34%)
SAIDs w/ High CVSS3 range 7-10: 220 (56.27%)
The month of November saw a lower number of advisories issued as compared to past months while Google Chrome and Internet Explorer vulnerabilities stole the headlines. Many enterprises were caught off-guard with the Google Chrome Zero-day advisory during the holiday period. Vulnerabilities in the Open Source Operating system mainly Linux and other software are on the rise while Microsoft vulnerabilities are declining. Microsoft follows its Patch Tuesday religiously which helps enterprises to devise an effective patch management strategy for Microsoft estate while third party patch management remains the Achilles’ heel for most enterprises.
