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') •
CVE-2021-20188 – podman: container users permissions are not respected in privileged containers
https://notcve.org/view.php?id=CVE-2021-20188
A flaw was found in podman before 1.7.0. File permissions for non-root users running in a privileged container are not correctly checked. This flaw can be abused by a low-privileged user inside the container to access any other file in the container, even if owned by the root user inside the container. It does not allow to directly escape the container, though being a privileged container means that a lot of security features are disabled when running the container. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. • https://bugzilla.redhat.com/show_bug.cgi?id=1915734 https://access.redhat.com/security/cve/CVE-2021-20188 • CWE-863: Incorrect Authorization •
