AI Analysis
Technical Summary
This advisory covers two security vulnerabilities in Apache Tomcat's EncryptInterceptor. CVE-2026-29146 is an information disclosure vulnerability caused by a Padding Oracle attack vector, allowing attackers to potentially decrypt sensitive data. CVE-2026-34486 involves a bypass of the EncryptInterceptor, resulting in missing encryption of sensitive data. Red Hat has released updated Tomcat packages (version 9.0.87-2.el9_4) for Red Hat Enterprise Linux 9.4 Update Services for SAP Solutions and related architectures to address these issues. The advisory rates the impact as Important (high severity) and provides links for applying the update.
Potential Impact
Successful exploitation of CVE-2026-29146 could lead to unauthorized disclosure of sensitive information due to a Padding Oracle vulnerability in the EncryptInterceptor. CVE-2026-34486 could allow sensitive data to be transmitted or stored without proper encryption because of an EncryptInterceptor bypass. Both vulnerabilities compromise the confidentiality of data handled by Apache Tomcat in affected Red Hat Enterprise Linux 9.4 environments.
Mitigation Recommendations
Red Hat has released updated Apache Tomcat packages (version 9.0.87-2.el9_4) that fix these vulnerabilities.
