openssl - Security Vulnerability

Hello Guys,
First of all, thanks for the lib !
Just wanted to share that we're getting a vulnerability report from this image. Details are as follows:
Server or client applications that call the SSL_check_chain() function during or after a TLS 1.3 handshake may crash due to a NULL pointer dereference as a result of incorrect handling of the "signature_algorithms_cert" TLS extension. The crash occurs if an invalid or unrecognised signature algorithm is received from the peer. This could be exploited by a malicious peer in a Denial of Service attack. OpenSSL version 1.1.1d, 1.1.1e, and 1.1.1f are affected by this issue. This issue did not affect OpenSSL versions prior to 1.1.1d. Fixed in OpenSSL 1.1.1g (Affected 1.1.1d-1.1.1f).
Seems like it's easily fixable by updating the OpenSSL lib version to 1.1.1g-r0 so your help would be greatly appreciated !
