Summary
Red Hat Security Advisory: Red Hat JBoss Core Services Apache HTTP Server 2.4.62 SP1 security update

Notes

Topic
Red Hat JBoss Core Services Apache HTTP Server 2.4.62 Service Pack 1 is now 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 packaged under Red Hat JBoss Core Services, to allow for faster distribution of updates and for a more consistent update experience. This release of Red Hat JBoss Core Services Apache HTTP Server 2.4.62 Service Pack 1 serves as a replacement for Red Hat JBoss Core Services Apache HTTP Server 2.4.62, and includes bug fixes and enhancements, which are documented in the Release Notes linked to in the References section. Security Fix(es): * expat: Improper Restriction of XML Entity Expansion Depth in libexpat [jbcs-httpd-2.4] (CVE-2024-8176) * httpd: HTTP Session Hijack via a TLS upgrade [jbcs-httpd-2.4] (CVE-2025-49812) * httpd: access control bypass by trusted clients is possible using TLS 1.3 session resumption [jbcs-httpd-2.4] (CVE-2025-23048) * httpd: insufficient escaping of user-supplied data in mod_ssl [jbcs-httpd-2.4] (CVE-2024-47252) * httpd: untrusted input from a client causes an assertion to fail in the Apache mod_proxy_http2 module [jbcs-httpd-2.4] (CVE-2025-49630) * libxml2: Out-of-Bounds Read in libxml2 [jbcs-httpd-2.4] (CVE-2025-32414) * libxml2: Out-of-bounds Read in xmlSchemaIDCFillNodeTables [jbcs-httpd-2.4] (CVE-2025-32415) * jbcs-httpd24-mod_security: ModSecurity Has Possible DoS Vulnerability [jbcs-httpd-2.4] (CVE-2025-47947) A Red Hat Security Bulletin which addresses further details about this flaw is available in the References section. 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.

This build configuration blocks the possibility of an attacker gaining arbitrary code execution even if a stack-clash vulnerability, like this one, could be exploited.\n\nThis vulnerability is rated Moderate because Red Hat builds use the `-fstack-clash-protection` compiler flag, which mitigates the risk of arbitrary code execution from stack overflows. While the flaw allows a crash via uncontrolled recursion in XML parsing, the hardened stack layout prevents reliable memory corruption, limiting the impact to a Denial of Service (DoS) scenario.\n\nWithin regulated environments, a combination of the following controls acts as a significant barrier to successfully exploiting a CWE-674: Uncontrolled Recursion vulnerability and therefore downgrades the severity of this particular CVE from Moderate to Low.\n\nInput validation controls ensure that inputs triggering recursion are validated to stay within safe limits, which reduces the risk of infinite or excessive recursion. The implementation of least functionality on the platform further restricts potential impacts of recursions by disabling unnecessary recursive functions or features, thus reducing the available pathways for a would-be attacker. The inclusion of developer testing and evaluation ensures that recursive functions are tested and that safeguards like error handling are in place. In the case of successful exploitation, detection and containment controls are in place to limit impacts by alerting on anomalous system behavior in real time, while process isolation can limit impacts to a single process.",

The flaw only occurs in non-default logging configurations where administrators explicitly use CustomLog directives with %{varname}x or %{varname}c to log mod_ssl variables like SSL_TLS_SNI, which limits the exposure. While an attacker-controlled TLS client can inject escape or control characters into the logs, potentially leading to log injection or misleading log entries, this does not allow execution of arbitrary code or compromise of the server itself. Furthermore, successful exploitation requires the attacker to craft specific TLS-level parameters, and there are no direct security consequences unless the logs are processed by downstream systems that are themselves vulnerable.",
