Exploitation
No exploitation in the wild and no public exploit is recorded for the CVEs named.

IPA issued an advisory regarding a buffer overflow vulnerability in OpenSSL, an open-source library providing SSL/TLS functionality. The flaw occurs during X.509 certificate verification processing, where a specially crafted malicious certificate could trigger a buffer overflow, potentially leading to denial-of-service conditions or remote code execution.

OpenSSL versions 1.1.1 and 1.0.2 are not affected by this issue. The developers have released updated versions that address the vulnerability, and IPA urges affected organizations to update to the latest versions promptly given the potential for expanded exploitation.

What this brief leaves out

This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.

It sits in a corpus of 16,436 reports from 149 sources, 661 of them written in the last seven days, and it grows through the day.

A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
