DSA-6493-1 libevent - security update

Several vulnerabilities were discovered in libevent, an asynchronous event notification library. The HTTP implementation (evhttp) handled Transfer-Encoding and Content-Length headers, chunked-encoding line terminators, header line folding and chunked trailers too permissively, which could allow HTTP request smuggling, header injection or access control bypass when a libevent-based server or client is combined with an HTTP proxy. Out-of-bounds memory accesses in the DNS (evdns), tagged RPC (evtag/evrpc) and buffered socket (bufferevent) code, and a use-after-free in evbuffer, could result in denial of service or potentially the execution of arbitrary code when processing untrusted input. https://security-tracker.debian.org/tracker/DSA-6493-1

Red Hat Security Advisory: Red Hat OpenShift distributed tracing platform (Tempo) 3.9.2 release

Red Hat OpenShift distributed tracing platform (Tempo) 3.9.2 has been released This release of the Red Hat OpenShift distributed tracing platform (Tempo) provides security improvements and bug fixes. Breaking changes: * None. Deprecations: * None. Technology Preview features: * None. Enhancements: * None. Bug fixes: * gRPC-Go authorization bypass vulnerability fix: Previously, gRPC-Go was vulnerable to an authorization bypass attack. This issue occurred because the HTTP/2 :path pseudo-header was not properly validated. Remote attackers could send raw HTTP/2 frames with a malformed :path that omitted the mandatory leading slash to bypass defined security policies. With this update, gRPC-Go properly validates the :path pseudo-header and rejects malformed requests. As a result, attackers can no longer bypass security policies to gain unauthorized access to services or disclose information. For more information, see https://access.redhat.com/security/cve/cve-2026-33186. * XPath component fix: Previously, the github.com/antchfx/xpath component did not properly handle certain Boolean XPath expressions. A remote attacker could submit a crafted expression that caused an infinite loop, resulting in 100% CPU utilization and a denial-of-service condition. With this update, the XPath component correctly processes Boolean expressions that evaluate to true. The system no longer enters an infinite loop when handling these expressions. For more information, see https://access.redhat.com/security/cve/cve-2026-4645. * Go JOSE denial-of-service vulnerability fix: Previously, the Go JOSE library for handling JSON Web Encryption (JWE) objects was vulnerable to a denial-of-service (DoS) attack. This issue occurred because the application failed when decrypting a specially crafted JWE object that specified a key wrapping algorithm but contained an empty encrypted key field. With this update, Go JOSE properly validates the encrypted key field before decryption. As a result, the application no longer crashes when processing malformed JWE objects, and the service remains available to legitimate users. For more information, see https://access.redhat.com/security/cve/cve-2026-34986. * Lodash _.template function fix: Previously, the lodash _.template function validated the variable option but did not validate options.imports key names. Both options passed values to the same code execution path. An attacker with the ability to control options.imports key names or pollute Object.prototype could exploit this gap to execute arbitrary code. With this update, lodash validates options.imports key names by using the same rules applied to the variable option. The _.template function rejects invalid key names and prevents code injection through this path. For more information, see https://access.redhat.com/security/cve/cve-2026-4800. * Go crypto/x509 and crypto/tls packages fix: Previously, the Go standard library crypto/x509 and crypto/tls packages did not limit the number of intermediate certificates processed during certificate chain building. An attacker could provide an excessive number of intermediate certificates, causing the system to perform an uncontrolled amount of work and resulting in a denial-of-service condition. With this update, the packages limit the number of intermediate certificates accepted during certificate chain validation. The system rejects certificate chains that exceed this limit. For more information, see https://access.redhat.com/security/cve/cve-2026-32280. * Go Root.Chmod function fix: Previously, the Root.Chmod function in the Go standard library internal/syscall/unix package had a race condition between checking and modifying a target file. An attacker could replace the target with a symbolic link after the check but before the operation completed, causing the permission change to apply to the linked file instead. This allowed an attacker to bypass directory restrictions and change permissions on unintended files. With this update

Breaking changes: * None Deprecations: * None Technology Preview features: * None Enhancements: * None Bug fixes: * XPath library vulnerability is fixed: Previously, the 'github.com/antchfx/xpath' library was vulnerable to a denial of service (DoS) attack. This issue occurred because specially crafted boolean XPath expressions that evaluated to true caused an infinite loop in the 'logicalQuery.Select' function, leading to 100% CPU utilization.

No known workaround exists. For more information, see https://issues.redhat.com/browse/TRACING-5963.
