Comment 5 John Helmert III 2022-03-19 05:19:30 UTC
Why did it take so long for CVE-2021-23165 (this bug) and CVE-2021-23158 (bug 1967018) to be released? The bugs were opened in 2021-06 but CVEs were released in 2022-03, 9 months later. This is a big gap for those who depend on on CVEs to know what needs to be patched.
