Red Hat Security Advisory: Red Hat build of Cryostat 4.2.0: new RHEL 9 container image security update
The Cryostat 4 on RHEL 9 container images have been updated to fix several bugs. Users of Cryostat 4 on RHEL 9 container images are advised to upgrade to these updated images, which contain backported patches to fix these bugs and add these enhancements. Users of these images are also encouraged to rebuild all container images that depend on these images. Security Fix(es): * golang.org/x/image: Denial of Service via malformed WEBP image parsing (CVE-2026-33813) * follow-redirects: Information disclosure via cross-domain redirects (CVE-2026-40895) * io.quarkus:quarkus-vertx-http: Authorization bypass via semicolons in HTTP requests (CVE-2026-39852) * github.com/jackc/pgx: Memory-safety vulnerability (CVE-2026-33815, CVE-2026-33816) * github.com/go-jose/go-jose: Go JOSE: Denial of Service via crafted JSON Web Encryption (JWE) object (CVE-2026-34986) * lodash: Arbitrary code execution via untrusted input in template imports (CVE-2026-4800) * netty: Denial of Service via HTTP/2 CONTINUATION frame flood (CVE-2026-33871) * io.netty/netty-codec-http: Request smuggling via incorrect parsing of HTTP/1.1 chunked transfer encoding extension values (CVE-2026-33870) * path-to-regexp: Denial of Service via crafted regular expressions (CVE-2026-4926) * undici: HTTP Request Smuggling and Denial of Service due to duplicate Content-Length headers (CVE-2026-1525) * google.golang.org/grpc: gRPC-Go: Authorization bypass due to improper HTTP/2 path validation (CVE-2026-33186) * undici: Denial of Service via unbounded memory consumption during WebSocket permessage-deflate decompression (CVE-2026-1526) * undici: Denial of Service via invalid WebSocket permessage-deflate extension parameter (CVE-2026-2229) * undici: Denial of Service via crafted WebSocket frame with large length (CVE-2026-1528) * io.vertx/vertx-core: static handler component cache can be manipulated to deny the access to static files (CVE-2026-1002) You can find images updated by this advisory in the Red Hat Container Catalog (see the References section).
AI Analysis
Technical Summary
This advisory covers a security update for Red Hat build of Cryostat 4.2.0 on RHEL 9 container images that addresses 16 distinct vulnerabilities affecting multiple third-party libraries and components such as golang.org/x/image, follow-redirects, io.quarkus, github.com/jackc/pgx, github.com/go-jose/go-jose, lodash, netty, path-to-regexp, undici, google.golang.org/grpc, and io.vertx/vertx-core. The vulnerabilities include denial of service via malformed inputs and resource exhaustion, authorization bypasses due to improper HTTP/2 path validation and semicolon parsing, information disclosure through cross-domain redirects, memory safety issues, HTTP request smuggling, and arbitrary code execution via untrusted template inputs. The update provides backported patches to fix these bugs and enhance security. Users should upgrade to Cryostat 4.2.0 container images on RHEL 9 and rebuild any dependent container images.
Potential Impact
The vulnerabilities collectively pose risks including denial of service conditions, unauthorized access bypasses, information disclosure, memory safety violations, HTTP request smuggling attacks, and arbitrary code execution. These issues could impact the confidentiality, integrity, and availability of systems running affected Cryostat 4 container images on RHEL 9. The severity of these vulnerabilities is rated as high by Red Hat Product Security.
Mitigation Recommendations
A patch is available in the form of updated Cryostat 4.2.0 container images for RHEL 9. Users should upgrade to these updated images from the Red Hat Container Registry and rebuild all container images that depend on them. This update contains backported fixes for all listed vulnerabilities. No additional mitigation steps are indicated beyond applying the updated container images.
