Project Zero won't share technical details of a vulnerability for 30 days if a vendor patches it before the 90-day or 7-day deadline. The 30-day period is intended for user patch adoption. https://googleprojectzero.blogspot.com/2021/04/policy-and-disclosure-2021-edition.html <https://googleprojectzero.blogspot.com/2021/04/policy-and-disclosure-2021-edition.html> Since OpenJDK released patches for this vulnerability today, PZ would publish technical details in 30 days. https://openjdk.org/groups/vulnerability/advisories/2022-07-19 <https://openjdk.org/groups/vulnerability/advisories/2022-07-19> — Regards, Roxana Content of type "text/html" skipped Download attachment "signature.asc" of type "application/pgp-signature" (834 bytes)
