There is no fixed version for RHEL:10 erlang-syntax_tools.

NVD Description

Note: Versions mentioned in the description apply only to the upstream erlang-syntax_tools package and not the erlang-syntax_tools package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

The Erlang otp TLS server answers with different TLS alerts to different error types in the RSA PKCS #1 1.5 padding. This allows an attacker to decrypt content or sign messages with the server's private key (this is a variation of the Bleichenbacher attack).
