CVSS: 7.7EPSS: 0%CPEs: 29EXPL: 0CVE-2019-3900 – Kernel: vhost_net: infinite loop while receiving packets leads to DoS
https://notcve.org/view.php?id=CVE-2019-3900
An infinite loop issue was found in the vhost_net kernel module in Linux Kernel up to and including v5.1-rc6, while handling incoming packets in handle_rx(). It could occur if one end sends packets faster than the other end can process them. A guest user, maybe remote one, could use this flaw to stall the vhost_net kernel thread, resulting in a DoS scenario. Se encontró un problema de bucle infinito en el módulo del núcleo vhost_net en el kernel de Linux versiones anteriores a 5.1-rc6 inclusive, mientras manejaba los paquetes entrantes en handle_rx(). Puede ocurrir cuando un extremo envía los paquetes más rápido de lo que el otro extremo los procesa. • http://packetstormsecurity.com/files/155212/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://www.securityfocus.com/bid/108076 https://access.redhat.com/errata/RHSA-2019:1973 https://access.redhat.com/errata/RHSA-2019:2029 https://access.redhat.com/errata/RHSA-2019:2043 https://access.redhat.com/errata/RHSA-2019:3220 https://access.redhat.com/errata/RHSA-2019:3309 https://access.redhat.com/errata/RHSA-2019:3517 https://access.redhat.com/errata/RHSA-2019:3836 http • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

Vulnerability in the MySQL Server component of Oracle MySQL (subcomponent: Server: Security: Privileges). Supported versions that are affected are 5.6.43 and prior, 5.7.25 and prior and 8.0.15 and prior. Easily exploitable vulnerability allows high privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server.

CVSS: 7.4EPSS: 0%CPEs: 33EXPL: 0CVE-2019-0223 – qpid-proton: TLS Man in the Middle Vulnerability
https://notcve.org/view.php?id=CVE-2019-0223
While investigating bug PROTON-2014, we discovered that under some circumstances Apache Qpid Proton versions 0.9 to 0.27.0 (C library and its language bindings) can connect to a peer anonymously using TLS *even when configured to verify the peer certificate* while used with OpenSSL versions before 1.1.0. This means that an undetected man in the middle attack could be constructed if an attacker can arrange to intercept TLS traffic. Mientras investigábamos el error PROTON-2014, descubrimos que en algunas circunstancias las versiones de Apache Qpid Proton 0.9 a 0.27.0 (librería de C y sus adaptaciones de lenguaje) pueden conectarse a un peer de forma anónima utilizando TLS *incluso cuando está configurado para verificar el certificado del peer* mientras se utiliza con versiones de OpenSSL anteriores a la 1.1.0. Esto significa que un ataque man in the middle podría ser construido si un atacante puede interceptar el tráfico TLS. A cryptographic weakness was discovered in qpid-proton's use of TLS. • http://www.openwall.com/lists/oss-security/2019/04/23/4 http://www.securityfocus.com/bid/108044 https://access.redhat.com/errata/RHSA-2019:0886 https://access.redhat.com/errata/RHSA-2019:1398 https://access.redhat.com/errata/RHSA-2019:1399 https://access.redhat.com/errata/RHSA-2019:1400 https://access.redhat.com/errata/RHSA-2019:2777 https://access.redhat.com/errata/RHSA-2019:2778 https://access.redhat.com/errata/RHSA-2019:2779 https://access.redhat.com/errata/ • CWE-300: Channel Accessible by Non-Endpoint •
