An issue was discovered in the Linux kernel before 5.0.4. There is a use-after-free upon attempted read access to /proc/ioports after the ipmi_si module is removed, related to drivers/char/ipmi/ipmi_si_intf.c, drivers/char/ipmi/ipmi_si_mem_io.c, and drivers/char/ipmi/ipmi_si_port_io.c. Fue descubierto en un fallo en el kernel de Linux anterior a 5.0.4. Hay un uso después de liberación de memoria, una vez que intenta acceder a la lectura del modulo proc/ioports after the ipmi_si es eliminado, relacionado adrivers/char/ipmi/ipmi_si_intf.c, drivers/char/ipmi/ipmi_si_mem_io.c, y drivers/char/ipmi/ipmi_si_port_io.c. A flaw was found in the Linux kernel's implementation of IPMI (remote baseband access). • http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00071.html http://www.securityfocus.com/bid/108410 https://access.redhat.com/errata/RHSA-2019:1873 https://access.redhat.com/errata/RHSA-2019:1891 https://access.redhat.com/errata/RHSA-2019:1959 https://access.redhat.com/errata/RHSA-2019:1971 https://access.redhat.com/errata/RHSA-2019:4057 https://access.redhat.com/errata/RHSA-2019:4058 https://access.redhat.com/errata/RHSA-2020:0036 https://cdn.kernel.org • CWE-416: Use After Free •
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 •

https://notcve.org/view.php?id=CVE-2019-11235
FreeRADIUS before 3.0.19 mishandles the "each participant verifies that the received scalar is within a range, and that the received group element is a valid point on the curve being used" protection mechanism, aka a "Dragonblood" issue, a similar issue to CVE-2019-9498 and CVE-2019-9499. FreeRADIUS versión anterior a 3.0.19 no maneja correctamente el mecanismo de protección "cada participante verifica que el escalar recibido está dentro de un rango, y que el elemento de grupo recibido es un punto válido en la curva que se está utilizando", alias "Dragonblood", este problema es similar a CVE-2019-9498 y CVE-2019-9499. A vulnerability was found in FreeRadius. An invalid curve attack allows an attacker to authenticate as any user, without knowing the password. FreeRADIUS doesn't verify whether the received elliptic curve point is valid. • http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00014.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00032.html http://lists.opensuse.org/opensuse-security-announce/2020-04/msg00033.html https://access.redhat.com/errata/RHSA-2019:1131 https://access.redhat.com/errata/RHSA-2019:1142 https://bugzilla.redhat.com/show_bug.cgi?id=1695748 https://freeradius.org/release_notes/?br=3.0.x&re=3.0.19 https://freeradius.org/security https://papers.math • CWE-345: Insufficient Verification of Data Authenticity •

https://notcve.org/view.php?id=CVE-2019-3878
A vulnerability was found in mod_auth_mellon before v0.14.2. If Apache is configured as a reverse proxy and mod_auth_mellon is configured to only let through authenticated users (with the require valid-user directive), adding special HTTP headers that are normally used to start the special SAML ECP (non-browser based) can be used to bypass authentication. Se ha detectado una vulnerabilidad en mod_auth_mellon, en versiones anteriores a la v0.14.2. Si Apache está configurado como proxy inverso y mod_auth_mellon está configurado para que solo deje acceder a los usuarios autenticados (con la directiva "require valid-user"), la adición de cabeceras HTTP especiales que se suelen emplear para iniciar el SAML ECP especial (no basado en el navegador) puede emplearse para omitir la autenticación.
