OpenSSL patches are out – CRITICAL bug downgraded to HIGH, but patch anyway!

OpenSSL 1.1.1 goes to version 1.1.1s, and patches one listed security-related bug, but this bug doesn’t have a security rating or an official CVE number.

OpenSSL 3.0 goes to version 3.0.7, and patches not one but two CVE-numbered security bugs that are official designated at HIGH severity.

We strongly recommend that you update, with as much urgency as you can muster, but the CRITICAL fix that everyone has been talking about has now been downgraded to HIGH severity.

The original bug only allows an attacker to corrupt four bytes on the stack, which limits the exploitability of the hole, while the second bug allows an unlimited amout of stack overflow, but apparently only of the “Dot” character repeated over and over again.

As mentioned above, you need OpenSSL 1.1.1s or OpenSSL 3.0.7 to replace whatever version you have at the moment.

OpenSSL 1.1.1s gets a security patch described as fixing “a regression introduced in OpenSSL 1.1.1r not refreshing the certificate data to be signed before signing the certificate”, that bug doesn’t have a severity or a CVE assigned to it.
