The OpenSSL team have released an advisory to upgrade to version 1.1.0c.
Read the notice here: “https://www.openssl.org/news/secadv/20161110.txt”.
Redhat’s article can be found here: “https://access.redhat.com/security/cve/cve-2016-7054”.
Severity: High TLS connections using *-CHACHA20-POLY1305 ciphersuites are susceptible to a DoS attack by corrupting larger payloads. This can result in an OpenSSL crash. This issue is not considered to be exploitable beyond a DoS. OpenSSL 1.1.0 users should upgrade to 1.1.0c
Sadly Redhat doesn’t use the same version numbers as the OpenSSL team but according to the Redhat article above, RHEL 7 is not susceptible to this. I’d recommend to upgrade to the latest version anyway.
