Attracting more than a half-million annual readers, this is the security community's go-to destination for technical breakdowns of the latest threats, critical vulnerability disclosures and cutting-edge research.

Patch Tuesday, May 2020

May's Patch Tuesday includes patches for 111 unique CVEs. Of those CVEs 17 are rated "Critical" and 94 rated as "Important". Aside from the common vulnerabilities in Microsoft's scripting engine, Sharepoint is the hardest hit on the "Critical" list with four separate Remote Code Execution (RCE) vulnerabilities and an Information Disclosure vulnerability patched for that server package. That "Critical" list also patches an RCE vulnerability in Visual Studio, specifically for an extension to provide Python support.

Included in the list of "Important" vulnerabilities are multiple RCE vulnerabilities for the JET Database engine used as a backend for multiple Microsoft products from the legacy Access Database to the more modern SQL Server Express. In addition, a dozen Elevation of Privilege vulnerabilities are patched in Windows Runtime that could allow an attacker to develop a malicious application that could run additional arbitrary code in an elevated context like Administrator or System. An additional dozen Elevation of Privilege vulnerabilities are patched in the Windows State Repository Service which tracks Microsoft web browsing activity in the Edge browser.

Luckily none of these vulnerabilities have been exposed or exploited in the wild yet, so now's the time to get patching before exploits are written.

Stay safe out there!
