NVD Description
Note: Versions mentioned in the description apply only to the upstream erlang-ic package and not the erlang-ic package as distributed by RHEL.
See How to fix? for RHEL:7 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).
