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 •

An infinite loop flaw was found in the USB xHCI controller emulation of QEMU while computing the length of the Transfer Request Block (TRB) Ring. This flaw allows a privileged guest user to hang the QEMU process on the host, resulting in a denial of service. Se ha encontrado un fallo de bucle infinito en la emulación del controlador USB xHCI de QEMU mientras es calculada la longitud del anillo de petición de transferencia (TRB). Este fallo permite a un usuario invitado privilegiado colgar el proceso de QEMU en el host, resultando en una denegación de servicio. • https://bugzilla.redhat.com/show_bug.cgi?id=1908004 https://gitlab.com/qemu-project/qemu/-/issues/646 https://lists.debian.org/debian-lts-announce/2023/03/msg00013.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/I7J5IRXJYLELW7D43A75LOWRUE5EU54O • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
