Red Hat has released a security update for the Red Hat Build of Apache Camel 4. 14. 4 for Spring Boot addressing multiple vulnerabilities. These include a flaw in undertow-core that fails to reject malformed Host headers, potentially enabling cache poisoning and SSRF (CVE-2025-12543); a vertx-core static handler cache manipulation vulnerability (CVE-2026-1002); and two arbitrary code execution vulnerabilities via JNDI dereferencing and deserialization in mchange-commons-java (CVE-2026-27727) and c3p0 (CVE-2026-27830). The update is rated as important by Red Hat Product Security. Users are advised to apply this patch after ensuring all prior errata are installed.

Red Hat Satellite 6. 17. 8 includes multiple security fixes addressing vulnerabilities in components such as python-pillow, candlepin, python-markdown, python-pyOpenSSL, and rubygem-activesupport. These vulnerabilities range from denial of service conditions to out-of-bounds writes and arbitrary code execution. The update also resolves several bugs related to certificate handling, HTTPS enforcement, registration commands, and UI issues. This advisory covers Red Hat Satellite 6. 17 for RHEL 9 and related components.

Red Hat Satellite 6. 16. 8 for RHEL 8 and 9 addresses multiple security vulnerabilities including denial of service, out-of-bounds write, arbitrary code execution, and buffer overflow issues across several components such as python-markdown, python-pillow, candlepin, python-pyOpenSSL, and rubygem-activesupport. These vulnerabilities could impact system stability and security if exploited. The advisory also includes various bug fixes improving security and functionality. Red Hat has released an update to remediate these issues.

mchange-commons-java, a library that provides Java utilities, includes code that mirrors early implementations of JNDI functionality, including support for remote `factoryClassLocation` values, by which code can be downloaded and invoked within a running application. If an attacker can provoke an application to read a maliciously crafted `jaxax.naming.Reference` or serialized object, they can provoke the download and execution of malicious code. Implementations of this functionality within the JDK were disabled by default behind a System property that defaults to `false`, `com.sun.jndi.ldap.object.trustURLCodebase`. However, since mchange-commons-java includes an independent implementation of JNDI derefencing, libraries (such as c3p0) that resolve references via that implementation could be provoked to download and execute malicious code even after the JDK was hardened. Mirroring the JDK patch, mchange-commons-java's JNDI functionality is gated by configuration parameters that default to restrictive values starting in version 0.4.0. No known workarounds are available. Versions prior to 0.4.0 should be avoided on application CLASSPATHs.
