Red Hat Security Advisory: tomcat security update
Two security vulnerabilities affecting Apache Tomcat in Red Hat Enterprise Linux 9.2 have been addressed. The first is an information disclosure issue via a Padding Oracle vulnerability in the EncryptInterceptor component (CVE-2026-29146). The second involves missing encryption of sensitive data due to an EncryptInterceptor bypass (CVE-2026-34486). Red Hat has released updated Tomcat packages to remediate these issues.
AI Analysis
Technical Summary
Red Hat Product Security issued an advisory (RHSA-2026:36878) for Apache Tomcat in Red Hat Enterprise Linux 9.2 addressing two vulnerabilities: CVE-2026-29146, a Padding Oracle vulnerability in the EncryptInterceptor that could lead to information disclosure, and CVE-2026-34486, which allows bypassing encryption of sensitive data via the EncryptInterceptor. The advisory provides updated Tomcat packages (version 9.0.87-2.el9_2) that fix these issues. The vulnerabilities are rated as having an important security impact by Red Hat. No CVSS scores are provided in the advisory, but the issues relate to cryptographic weaknesses and data protection failures.
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 remain unencrypted due to an EncryptInterceptor bypass, potentially exposing confidential information. Both vulnerabilities compromise the confidentiality of data handled by Apache Tomcat.
Mitigation Recommendations
Red Hat has released updated Tomcat packages (version 9.0.87-2.el9_2) for Red Hat Enterprise Linux 9.2 that address these vulnerabilities. Users should apply these official updates as detailed in Red Hat advisory RHSA-2026:36878 and the referenced article https://access.redhat.com/articles/11258. No additional mitigations are specified or required beyond applying the provided patches.
