Incomplete cleanup from specific special register read operations in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. Una limpieza incompleta de operaciones de lectura de un registro especial específico en algunos Intel® Processors puede permitir a un usuario autenticado habilitar potencialmente una divulgación de información por medio de un acceso local A new domain bypass transient execution attack known as Special Register Buffer Data Sampling (SRBDS) has been found. This flaw allows data values from special internal registers to be leaked by an attacker able to execute code on any core of the CPU. An unprivileged, local attacker can use this flaw to infer values returned by affected instructions known to be commonly used during cryptographic operations that rely on uniqueness, secrecy, or both. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00024.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00031.html http://www.openwall.com/lists/oss-security/2020/07/14/5 https://cert-portal.siemens.com/productcert/pdf/ssa-534763.pdf https://kc.mcafee.com/corporate/index?page=content&id=SB10318 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message • CWE-459: Incomplete Cleanup •
