CVSS: 7.5EPSS: 0%CPEs: 5EXPL: 0CVE-2022-22787 – Insufficient hostname validation during Clusterswitch message in Zoom Client for Meetings
https://notcve.org/view.php?id=CVE-2022-22787
The Zoom Client for Meetings (for Android, iOS, Linux, macOS, and Windows) before version 5.10.0 fails to properly validate the hostname during a server switch request. This issue could be used in a more sophisticated attack to trick an unsuspecting users client to connect to a malicious server when attempting to use Zoom services. Zoom Client for Meetings (para Android, iOS, Linux, macOS y Windows) anterior a la versión 5.10.0 no comprueba correctamente el nombre de host durante una petición de cambio de servidor. Este problema podría usarse en un ataque más sofisticado para engañar a un cliente de usuario desprevenido para que sea conectado a un servidor malicioso cuando intente usar los servicios de Zoom • http://packetstormsecurity.com/files/167238/Zoom-XMPP-Stanza-Smuggling-Remote-Code-Execution.html https://explore.zoom.us/en/trust/security/security-bulletin • CWE-295: Improper Certificate Validation •

x86: Speculative vulnerabilities with bare (non-shim) 32-bit PV guests 32-bit x86 PV guest kernels run in ring 1. At the time when Xen was developed, this area of the i386 architecture was rarely used, which is why Xen was able to use it to implement paravirtualisation, Xen's novel approach to virtualization. In AMD64, Xen had to use a different implementation approach, so Xen does not use ring 1 to support 64-bit guests. With the focus now being on 64-bit systems, and the availability of explicit hardware support for virtualization, fixing speculation issues in ring 1 is not a priority for processor companies. Indirect Branch Restricted Speculation (IBRS) is an architectural x86 extension put together to combat speculative execution sidechannel attacks, including Spectre v2. • https://xenbits.xenproject.org/xsa/advisory-370.txt • CWE-212: Improper Removal of Sensitive Information Before Storage or Transfer •

https://notcve.org/view.php?id=CVE-2020-8899
There is a buffer overwrite vulnerability in the Quram qmg library of Samsung's Android OS versions O(8.x), P(9.0) and Q(10.0). An unauthenticated, unauthorized attacker sending a specially crafted MMS to a vulnerable phone can trigger a heap-based buffer overflow in the Quram image codec leading to an arbitrary remote code execution (RCE) without any user interaction. The Samsung ID is SVE-2020-16747. Se presenta una vulnerabilidad de sobrescritura del búfer en la biblioteca Quram qmg del sistema operativo Android de Samsung versiones O(8.x), P(9.0) y Q(10.0). Un atacante no autenticado y no autorizado al enviar un MMS especialmente diseñado hacia un teléfono vulnerable puede desencadenar un desbordamiento del búfer en la región heap de la memoria en el códec de imagen de Quram conllevando a una ejecución de código remota (RCE) arbitraria sin ninguna interacción del usuario. • http://packetstormsecurity.com/files/157620/Samsung-Android-Remote-Code-Execution.html https://bugs.chromium.org/p/project-zero/issues/detail? • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
