Summary
Red Hat Security Advisory: Red Hat JBoss Web Server 3.1 Service Pack 11 security update

Notes

Topic
An update is now available for Red Hat JBoss Web Server 3.1 for RHEL 7. Red Hat Product Security has rated this release as having a security impact of Low. 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 Web Server is a fully integrated and certified set of components for hosting Java web applications. It is comprised of the Apache HTTP Server, the Apache Tomcat Servlet container, Apache Tomcat Connector (mod_jk), JBoss HTTP Connector (mod_cluster), Hibernate, and the Tomcat Native library. This release of Red Hat JBoss Web Server 3.1 Service Pack 11 serves as a replacement for Red Hat JBoss Web Server 3.1, and includes bug fixes, which are documented in the Release Notes document linked to in the References. Security Fix(es): * openssl: EDIPARTYNAME NULL pointer de-reference (CVE-2020-1971) 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.

OpenSSL itself uses the GENERAL_NAME_cmp function for two purposes, when comparing CRL distribution point names between an available CRL and a CRL distribution point embedded in an X509 certificate and when verifying that a timestamp response token signer matches the timestamp authority name (exposed via the API functions TS_RESP_verify_response and TS_RESP_verify_token). If an attacker can control both items being compared then that attacker could trigger a crash. For example, if the attacker can trick a client or server into checking a malicious certificate against a malicious CRL then a crash may be triggered.\n\nThird party applications compiled with openssl using the function GENERAL_NAME_cmp in a vulnerable way are affected by this flaw.\n\nGENERAL_NAME_cmp was added in 0.9.8k, therefore older versions of openssl are not affected by this flaw.",
