Senserva AI Opinion for CVE-2024-6197

Unusual among Windows CVEs, this one carries a HackerOne report title, marking it as a third-party component flaw: a memory corruption bug that frees a stack buffer in ASN.1 UTF-8 string handling (utf8asn1str). Microsoft ships the affected code in Windows 10 1809 and Windows Server 2019, rating it Critical at CVSS 9.0 with a 61 percent EPSS probability. Bugs that free stack memory are prime candidates for reliable exploitation.

Do this: Apply the Windows cumulative update to 1809 and Server 2019 hosts; the vulnerable library ships inside the OS itself.
