https://notcve.org/view.php?id=CVE-2020-6402
Insufficient policy enforcement in downloads in Google Chrome on OS X prior to 80.0.3987.87 allowed an attacker who convinced a user to install a malicious extension to execute arbitrary code via a crafted Chrome Extension. Una aplicación insuficiente de la política en downloads en Google Chrome sobre OS X versiones anteriores a 80.0.3987.87, permitió a un atacante que convenció a un usuario a instalar una extensión maliciosa para ejecutar código arbitrario por medio de una extensión de Chrome diseñada. • http://lists.opensuse.org/opensuse-security-announce/2020-02/msg00015.html http://lists.opensuse.org/opensuse-security-announce/2020-02/msg00025.html https://access.redhat.com/errata/RHSA-2020:0514 https://chromereleases.googleblog.com/2020/02/stable-channel-update-for-desktop.html https://crbug.com/1029375 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6IOHSO6BUKC6I66J5PZOMAGFVJ66ZS57 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/m • CWE-20: Improper Input Validation •
CVE-2020-1712 – systemd: use-after-free when asynchronous polkit queries are performed
https://notcve.org/view.php?id=CVE-2020-1712
A heap use-after-free vulnerability was found in systemd before version v245-rc1, where asynchronous Polkit queries are performed while handling dbus messages. A local unprivileged attacker can abuse this flaw to crash systemd services or potentially execute code and elevate their privileges, by sending specially crafted dbus messages. Se detectó una vulnerabilidad uso de la memoria previamente liberada de la pila en systemd versiones anteriores a v245-rc1, donde se llevaron a cabo consultas de Polkit asincrónicas mientras se manejan mensajes dbus. Un atacante no privilegiado local puede abusar de este fallo para bloquear los servicios de systemd o potencialmente ejecutar código y elevar sus privilegios, mediante el envío de mensajes dbus especialmente diseñados.

CVE-2020-1711 – QEMU: block: iscsi: OOB heap access via an unexpected response of iSCSI Server
https://notcve.org/view.php?id=CVE-2020-1711
An out-of-bounds heap buffer access flaw was found in the way the iSCSI Block driver in QEMU versions 2.12.0 before 4.2.1 handled a response coming from an iSCSI server while checking the status of a Logical Address Block (LBA) in an iscsi_co_block_status() routine. A remote user could use this flaw to crash the QEMU process, resulting in a denial of service or potential execution of arbitrary code with privileges of the QEMU process on the host. Se detectó una fallo de acceso al búfer de la pila fuera de límites en la manera en que el controlador de iSCSI Block versiones 2.xx de QEMU hasta 2.12.0 incluyéndola, manejó una respuesta proveniente de un servidor iSCSI mientras se comprobaba el estado de un Logical Address Block (LBA) en una rutina iscsi_co_block_status(). Un usuario remoto podría usar este fallo para bloquear el proceso de QEMU, resultando en una denegación de servicio o posible ejecución de código arbitrario con privilegios del proceso de QEMU en el host.

CVE-2019-20444 – netty: HTTP request smuggling
https://notcve.org/view.php?id=CVE-2019-20444
HttpObjectDecoder.java in Netty before 4.1.44 allows an HTTP header that lacks a colon, which might be interpreted as a separate header with an incorrect syntax, or might be interpreted as an "invalid fold." El archivo HttpObjectDecoder.java en Netty versiones anteriores a 4.1.44, permite un encabezado HTTP que carece de ":" dos puntos, que podría ser interpretado como un encabezado separado con una sintaxis incorrecta, o podría ser interpretado como un "invalid fold." A HTTP smuggling flaw was found in HttpObjectDecoder.java in Netty in versions prior to version 4.1.44. HTTP headers with an invalid fold, in this case CRLF (carriage return, line feed) without being followed by SP (space) or HTAB (horizontal tab), result in situations where headers can be misread. Data integrity is the highest threat with this vulnerability. • https://access.redhat.com/errata/RHSA-2020:0497 https://access.redhat.com/errata/RHSA-2020:0567 https://access.redhat.com/errata/RHSA-2020:0601 https://access.redhat.com/errata/RHSA-2020:0605 https://access.redhat.com/errata/RHSA-2020:0606 https://access.redhat.com/errata/RHSA-2020:0804 https://access.redhat.com/errata/RHSA-2020:0805 https://access.redhat.com/errata/RHSA-2020:0806 https://access.redhat.com/errata/RHSA-2020:0811 https://github.com/netty/netty/compare& • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
CVE-2019-20445 – netty: HttpObjectDecoder.java allows Content-Length header to accompanied by second Content-Length header
https://notcve.org/view.php?id=CVE-2019-20445
HttpObjectDecoder.java in Netty before 4.1.44 allows a Content-Length header to be accompanied by a second Content-Length header, or by a Transfer-Encoding header. "El archivo HttpObjectDecoder.java en Netty versiones anteriores a 4.1.44, permite que un encabezado Content-Length esté acompañado por un segundo encabezado Content-Length o por un encabezado Transfer-Encoding." A flaw was found in Netty before version 4.1.44, where it accepted multiple Content-Length headers and also accepted both Transfer-Encoding, as well as Content-Length headers where it should reject the message under such circumstances. In circumstances where Netty is used in the context of a server, it could result in a viable HTTP smuggling vulnerability. • https://access.redhat.com/errata/RHSA-2020:0497 https://access.redhat.com/errata/RHSA-2020:0567 https://access.redhat.com/errata/RHSA-2020:0601 https://access.redhat.com/errata/RHSA-2020:0605 https://access.redhat.com/errata/RHSA-2020:0606 https://access.redhat.com/errata/RHSA-2020:0804 https://access.redhat.com/errata/RHSA-2020:0805 https://access.redhat.com/errata/RHSA-2020:0806 https://access.redhat.com/errata/RHSA-2020:0811 https://github.com/netty/netty/compare& • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
