Technical Summary
This advisory covers security fixes for the Red Hat build of OpenTelemetry Collector, specifically addressing four vulnerabilities: CVE-2024-45336 involves sensitive HTTP headers being sent incorrectly after cross-domain redirects in the golang net/http package; CVE-2025-27144 is a denial of service vulnerability in the Go JOSE parsing library; CVE-2025-22868 concerns unexpected memory consumption during token parsing in golang.org/x/oauth2/jws; and CVE-2025-29786 relates to memory exhaustion in the Expr parser with unrestricted input. These issues affect the OpenTelemetry Collector packages distributed with Red Hat Enterprise Linux 9.4 Extended Update Support and related architectures. The advisory references fixes available in updated packages and directs users to Red Hat's update article for remediation instructions.
Potential Impact
The vulnerabilities could lead to sensitive header information leakage after cross-domain redirects, denial of service conditions due to parsing vulnerabilities, and memory exhaustion from uncontrolled input parsing. These impacts can affect the confidentiality and availability of systems running the affected OpenTelemetry Collector packages on Red Hat Enterprise Linux 9.4. No known exploits in the wild have been reported at this time.
Mitigation Recommendations
Red Hat has released updated packages for the OpenTelemetry Collector in Red Hat Enterprise Linux 9.4 Extended Update Support and related variants. Users should apply these official updates as described in Red Hat's advisory (RHSA-2025:3593) and the update instructions at https://access.redhat.com/articles/11258.
