Tripwire’s September 2021 Patch Priority Index (PPI) brings together important vulnerabilities from Microsoft, Adobe, Linux, and Confluence.
First on the patch priority list this month are patches for the Linux kernel (CVE-2021-3490) and Confluence Server and Data Center (CVE-2021-26084). Exploits for these vulnerabilities have been recently added to the Metasploit Exploit Framework. These systems should be patched as soon as possible.
Up next are patches for Microsoft Edge that resolve information disclosure and use after free vulnerabilities.
Next are patches for Microsoft Office, Excel, and Access. These patches resolve remote code execution and spoofing vulnerabilities.
