https://notcve.org/view.php?id=CVE-2021-20270
An infinite loop in SMLLexer in Pygments versions 1.5 to 2.7.3 may lead to denial of service when performing syntax highlighting of a Standard ML (SML) source file, as demonstrated by input that only contains the "exception" keyword. Un bucle infinito en SMLLexer en Pygments versiones 1.5 hasta 2.7.3, puede conllevar a una denegación de servicio cuando se lleva a cabo el resaltado de sintaxis de un archivo fuente de Standard ML (SML), como es demostrado por la entrada que solo contiene la palabra clave "exception" • https://bugzilla.redhat.com/show_bug.cgi?id=1922136 https://lists.debian.org/debian-lts-announce/2021/05/msg00003.html https://lists.debian.org/debian-lts-announce/2021/05/msg00006.html https://www.debian.org/security/2021/dsa-4889 https://www.oracle.com/security-alerts/cpuoct2021.html https://access.redhat.com/security/cve/CVE-2021-20270 • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

https://notcve.org/view.php?id=CVE-2020-27827
A flaw was found in multiple versions of OpenvSwitch. Specially crafted LLDP packets can cause memory to be lost when allocating data to handle specific optional TLVs, potentially causing a denial of service. The highest threat from this vulnerability is to system availability. Se encontró un fallo en múltiples versiones de OpenvSwitch. Los paquetes LLDP especialmente diseñados pueden causar que una memoria se pierda cuando se asignan datos para manejar TLV opcionales específicos, potencialmente causando una denegación de servicio. • https://bugzilla.redhat.com/show_bug.cgi?id=1921438 https://cert-portal.siemens.com/productcert/pdf/ssa-941426.pdf https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/3T5XHPOGIPWCRRPJUE6P3HVC5PTSD5JS https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JYA4AMJXCNF6UPFG36L2TPPT32C242SP https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/SKQWHG2SZJZSGC7PXVDAEJYBN7ESDR7D https://mail.openvswitch.org/pipermail/ovs-dev/2021&# • CWE-400: Uncontrolled Resource Consumption •
CVSS: 7.1EPSS: 0%CPEs: 9EXPL: 0CVE-2020-27781 – ceph: User credentials can be manipulated and stolen by Native CephFS consumers of OpenStack Manila
https://notcve.org/view.php?id=CVE-2020-27781
User credentials can be manipulated and stolen by Native CephFS consumers of OpenStack Manila, resulting in potential privilege escalation. An Open Stack Manila user can request access to a share to an arbitrary cephx user, including existing users. The access key is retrieved via the interface drivers. Then, all users of the requesting OpenStack project can view the access key. This enables the attacker to target any resource that the user has access to. • https://bugzilla.redhat.com/show_bug.cgi?id=1900109 https://lists.debian.org/debian-lts-announce/2023/10/msg00034.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ZJ7FFROL25FYRL6FMI33VRKOD74LINRP https://security.gentoo.org/glsa/202105-39 https://access.redhat.com/security/cve/CVE-2020-27781 • CWE-522: Insufficiently Protected Credentials •

https://notcve.org/view.php?id=CVE-2020-1690
An improper authorization flaw was discovered in openstack-selinux's applied policy where it does not prevent a non-root user in a container from privilege escalation. A non-root attacker in one or more Red Hat OpenStack (RHOSP) containers could send messages to the dbus. With access to the dbus, the attacker could start or stop services, possibly causing a denial of service. Versions before openstack-selinux 0.8.24 are affected. Se ha detectado un fallo de autorización inapropiada en la política aplicada de openstack-selinux, que no impide a un usuario no root en un contenedor pueda escalar sus privilegios. • https://bugzilla.redhat.com/show_bug.cgi?id=1789640 https://access.redhat.com/security/cve/CVE-2020-1690 • CWE-285: Improper Authorization •
