Summary
Red Hat Security Advisory: Red Hat JBoss Core Services Apache HTTP Server 2.4.37 Security Release

Notes

Topic
Red Hat JBoss Core Services Pack Apache Server 2.4.37 zip release for RHEL 6, RHEL 7 and Microsoft Windows is available. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
Red Hat JBoss Core Services is a set of supplementary software for Red Hat JBoss middleware products. This software, such as Apache HTTP Server, is common to multiple JBoss middleware products, and is packaged under Red Hat JBoss Core Services to allow for faster distribution of updates, and for a more consistent update experience. This release adds the new Apache HTTP Server 2.4.37 packages that are part of the JBoss Core Services offering. This release serves as a replacement for Red Hat JBoss Core Services Pack Apache Server 2.4.29 and includes bug fixes and enhancements. Refer to the Release Notes for information on the most significant bug fixes and enhancements included in this release. Security Fix(es): * openssl: RSA key generation cache timing vulnerability in crypto/rsa/rsa_gen.c allows attackers to recover private keys (CVE-2018-0737) * openssl: timing side channel attack in the DSA signature algorithm (CVE-2018-0734) * mod_auth_digest: access control bypass due to race condition (CVE-2019-0217) * openssl: Side-channel vulnerability on SMT/Hyper-Threading architectures (PortSmash) (CVE-2018-5407) * mod_session_cookie does not respect expiry time (CVE-2018-17199) * mod_http2: DoS via slow, unneeded request bodies (CVE-2018-17189) * mod_http2: possible crash on late upgrade (CVE-2019-0197) * mod_http2: read-after-free on a string compare (CVE-2019-0196) * nghttp2: HTTP/2: large amount of data request leads to denial of service (CVE-2019-9511) * nghttp2: HTTP/2: flood using PRIORITY frames resulting in excessive resource consumption (CVE-2019-9513) * mod_http2: HTTP/2: 0-length headers leads to denial of service (CVE-2019-9516) * mod_http2: HTTP/2: request for large response leads to denial of service (CVE-2019-9517) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
