CVSS: 9.0EPSS: 32%CPEs: 47EXPL: 21CVE-2019-14287 – sudo 1.8.27 - Security Bypass
https://notcve.org/view.php?id=CVE-2019-14287
In Sudo before 1.8.28, an attacker with access to a Runas ALL sudoer account can bypass certain policy blacklists and session PAM modules, and can cause incorrect logging, by invoking sudo with a crafted user ID. For example, this allows bypass of !root configuration, and USER= logging, for a "sudo -u \#$((0xffffffff))" command. En Sudo anteriores a 1.8.28, un atacante con acceso a una cuenta Runas ALL sudoer puede omitir ciertas listas negras de políticas y módulos PAM de sesión, y puede causar un registro incorrecto, mediante la invocación sudo con un ID de usuario creado. Por ejemplo, esto permite la omisión de la configuración root y el registro USER= para un comando "sudo -u \#$((0xffffffff))". • https://www.exploit-db.com/exploits/47502 https://github.com/n0w4n/CVE-2019-14287 https://github.com/shallvhack/Sudo-Security-Bypass-CVE-2019-14287 https://github.com/CMNatic/Dockerized-CVE-2019-14287 https://github.com/axax002/sudo-vulnerability-CVE-2019-14287 https://github.com/N3rdyN3xus/CVE-2019-14287 https://github.com/DewmiApsara/CVE-2019-14287 https://github.com/MariliaMeira/CVE-2019-14287 https://github.com/edsonjt81/CVE-2019-14287- https://github.com/SachinthaDeSilva-cmd& • CWE-267: Privilege Defined With Unsafe Actions CWE-755: Improper Handling of Exceptional Conditions •
CVSS: 7.4EPSS: 0%CPEs: 32EXPL: 1CVE-2019-14823 – JSS: OCSP policy "Leaf and Chain" implicitly trusts the root certificate
https://notcve.org/view.php?id=CVE-2019-14823
A flaw was found in the "Leaf and Chain" OCSP policy implementation in JSS' CryptoManager versions after 4.4.6, 4.5.3, 4.6.0, where it implicitly trusted the root certificate of a certificate chain. Applications using this policy may not properly verify the chain and could be vulnerable to attacks such as Man in the Middle. Se detectó un fallo en la implementación de la política OCSP "Leaf and Chain" en las versiones de CryptoManager de JSS versiones posteriores a 4.4.6, 4.5.3, 4.6.0, donde confiaba implícitamente en el certificado raíz de una cadena de certificados. Es posible que las aplicaciones que utilizan esta política no verifiquen correctamente la cadena y puedan ser vulnerables a ataques de tipo Man in the Middle.

https://notcve.org/view.php?id=CVE-2019-14835
A buffer overflow flaw was found, in versions from 2.6.34 to 5.2.x, in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could use this flaw to increase their privileges on the host. Se encontró un fallo de desbordamiento de búfer, en las versiones desde 2.6.34 hasta 5.2.x, en la manera en que la funcionalidad vhost del kernel de Linux que traduce los búferes virtueue en IOV, registraba los descriptores del búfer durante una migración. Un usuario invitado privilegiado capaz de pasar descriptores con una longitud no válida hacia el host cuando la migración está en marcha, podría usar este fallo para aumentar sus privilegios sobre el host.

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 •
