There is a use-after-free vulnerability in file pdd_simplifier.cpp in Z3 before 4.8.8. It occurs when the solver attempt to simplify the constraints and causes unexpected memory access. It can cause segmentation faults or arbitrary code execution. Existe una vulnerabilidad use-after-free en el archivo pdd_simplifier.cpp en Z3 antes de la versión 4.8.8. Ocurre cuando el solucionador intenta simplificar las restricciones y provoca un acceso inesperado a la memoria. • https://github.com/Z3Prover/z3/issues/3363 • CWE-416: Use After Free •
CVSS: 4.3EPSS: 0%CPEs: 385EXPL: 1CVE-2020-24588 – kernel: wifi frame payload being parsed incorrectly as an L2 frame
https://notcve.org/view.php?id=CVE-2020-24588
The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent Privacy (WEP) doesn't require that the A-MSDU flag in the plaintext QoS header field is authenticated. Against devices that support receiving non-SSP A-MSDU frames (which is mandatory as part of 802.11n), an adversary can abuse this to inject arbitrary network packets. El estándar 802.11 que sustenta a Wi-Fi Protected Access (WPA, WPA2, y WPA3) y Wired Equivalent Privacy (WEP) no requiere que el flag A-MSDU en el campo de encabezado QoS de texto plano esté autenticada. Contra dispositivos que admiten la recepción de tramas A-MSDU que no son SSP (que es obligatorio como parte de 802.11n), un adversario puede abusar de esto para inyectar paquetes de red arbitrarios A flaw was found in the Linux kernels wifi implementation. An attacker within wireless broadcast range can inject custom data into the wireless communication circumventing checks on the data. • http://www.openwall.com/lists/oss-security/2021/05/11/12 https://cert-portal.siemens.com/productcert/pdf/ssa-913875.pdf https://github.com/vanhoefm/fragattacks/blob/master/SUMMARY.md https://lists.debian.org/debian-lts-announce/2021/06/msg00019.html https://lists.debian.org/debian-lts-announce/2021/06/msg00020.html https://lists.debian.org/debian-lts-announce/2023/04/msg00002.html https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-wifi-faf-22epcEWu https: • CWE-20: Improper Input Validation CWE-327: Use of a Broken or Risky Cryptographic Algorithm •
