CVSS: 7.5EPSS: 10%CPEs: 9EXPL: 4CVE-2022-3602 – X.509 Email Address 4-byte Buffer Overflow
https://notcve.org/view.php?id=CVE-2022-3602
A buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint checking. Note that this occurs after certificate chain signature verification and requires either a CA to have signed the malicious certificate or for the application to continue certificate verification despite failure to construct a path to a trusted issuer. An attacker can craft a malicious email address to overflow four attacker-controlled bytes on the stack. This buffer overflow could result in a crash (causing a denial of service) or potentially remote code execution. Many platforms implement stack overflow protections which would mitigate against the risk of remote code execution. • https://github.com/colmmacc/CVE-2022-3602 https://github.com/eatscrayon/CVE-2022-3602-poc https://github.com/corelight/CVE-2022-3602 https://github.com/cybersecurityworks553/CVE-2022-3602-and-CVE-2022-3786 http://packetstormsecurity.com/files/169687/OpenSSL-Security-Advisory-20221101.html http://www.openwall.com/lists/oss-security/2022/11/01/15 http://www.openwall.com/lists/oss-security/2022/11/01/16 http://www.openwall.com/lists/oss-security/2022/11/01/17 http://www&# • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •

Observable discrepancy in the RAPL interface for some Intel(R) Processors may allow a privileged user to potentially enable information disclosure via local access. Una discrepancia observable en la interfaz RAPL para algunos Intel® Processors, puede habilitar a un usuario privilegiado para permitir potencialmente una divulgación de información por medio de un acceso local A vulnerability was found in Intel's implementation of RAPL (Running Average Power Limit). An attacker with a local account could query the power management functionality to intelligently infer SGX enclave computation values by measuring power usage in the RAPL subsystem. • https://lists.debian.org/debian-lts-announce/2021/02/msg00007.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/AQ24MFBVH3HJW3PNRQBRY4YXKC7GA57W https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GRFC7UAPKAFFH5WX3AMDUBVHLKYQA2NZ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MAAGIK5CXKBPGY3R4UR5VO56M7MKLZ43 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/NEM2FZWVE4FNGYNQU3WCBAWT • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-203: Observable Discrepancy •
