https://notcve.org/view.php?id=CVE-2020-27820
A vulnerability was found in Linux kernel, where a use-after-frees in nouveau's postclose() handler could happen if removing device (that is not common to remove video card physically without power-off, but same happens if "unbind" the driver). Se ha encontrado una vulnerabilidad en el kernel de Linux, en la que un uso de memoria previamente liberada en el manejador postclose() de nouveau podría ocurrir si se quita el dispositivo (que no es común quitar la tarjeta de vídeo físicamente sin apagar, pero lo mismo ocurre si se "desvincula" el controlador) • https://bugzilla.redhat.com/show_bug.cgi?id=1901726 https://lore.kernel.org/dri-devel/20201103194912.184413-2-jcline%40redhat.com https://lore.kernel.org/dri-devel/20201103194912.184413-3-jcline%40redhat.com https://lore.kernel.org/dri-devel/20201103194912.184413-4-jcline%40redhat.com https://www.oracle.com/security-alerts/cpujul2022.html https://access.redhat.com/security/cve/CVE-2020-27820 https://lore.kernel.org/dri-devel/20201103194912.184413-2-jcline@redhat.com https://lore.kernel.org • CWE-416: Use After Free •
CVSS: 5.3EPSS: 0%CPEs: 51EXPL: 0CVE-2021-25219 – Lame cache can be abused to severely degrade resolver performance
https://notcve.org/view.php?id=CVE-2021-25219
In BIND 9.3.0 -> 9.11.35, 9.12.0 -> 9.16.21, and versions 9.9.3-S1 -> 9.11.35-S1 and 9.16.8-S1 -> 9.16.21-S1 of BIND Supported Preview Edition, as well as release versions 9.17.0 -> 9.17.18 of the BIND 9.17 development branch, exploitation of broken authoritative servers using a flaw in response processing can cause degradation in BIND resolver performance. The way the lame cache is currently designed makes it possible for its internal data structures to grow almost infinitely, which may cause significant delays in client query processing. En BIND versiones 9.3.0 posteriores a 9.11.35, versiones 9.12.0 posteriores a 9.16.21, y en versiones 9.9.3-S1 posteriores a 9.11.35-S1 y versiones 9.16.8-S1 posteriores a 9.16.21-S1 de BIND Supported Preview Edition, así como en las versiones 9.17.0 -> 9.17.18 de la rama de desarrollo de BIND 9.17, una explotación de servidores autoritativos rotos usando un fallo en el procesamiento de respuestas puede causar una degradación en el rendimiento del resolver BIND. La forma en que está diseñada actualmente la caché de lame hace posible que sus estructuras de datos internas crezcan casi infinitamente, lo que puede causar retrasos significativos en el procesamiento de las consultas de los clientes A flaw was found in the way bind processes broken responses from authoritative servers. This caching mechanism could be abused by an attacker to significantly degrade resolver performance. • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://kb.isc.org/v1/docs/cve-2021-25219 https://lists.debian.org/debian-lts-announce/2021/11/msg00001.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/EF4NAVRV4H3W4GA3LGGZYUKD3HSJBAVW https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YGV7SA27CTYLGFJSPUM3V36ZWK7WWDI4 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YTKC4E3HUOLYN5 • CWE-20: Improper Input Validation •

jQuery-UI is the official jQuery user interface library. Prior to version 1.13.0, accepting the value of the `altField` option of the Datepicker widget from untrusted sources may execute untrusted code. The issue is fixed in jQuery UI 1.13.0. Any string value passed to the `altField` option is now treated as a CSS selector. A workaround is to not accept the value of the `altField` option from untrusted sources. jQuery-UI es la biblioteca oficial de interfaz de usuario de jQuery. • https://blog.jqueryui.com/2021/10/jquery-ui-1-13-0-released https://github.com/jquery/jquery-ui/pull/1954/commits/6809ce843e5ac4128108ea4c15cbc100653c2b63 https://github.com/jquery/jquery-ui/security/advisories/GHSA-9gj3-hwp5-pmwc https://lists.debian.org/debian-lts-announce/2022/01/msg00014.html https://lists.debian.org/debian-lts-announce/2023/08/msg00040.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HVKIOWSXL2RF2ULNAP7PHESYCFSZIJE3 https://lists.fedoraproj • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

CVSS: 7.8EPSS: 0%CPEs: 11EXPL: 1CVE-2021-21703 – PHP-FPM memory access in root process leading to privilege escalation
https://notcve.org/view.php?id=CVE-2021-21703
In PHP versions 7.3.x up to and including 7.3.31, 7.4.x below 7.4.25 and 8.0.x below 8.0.12, when running PHP FPM SAPI with main FPM daemon process running as root and child worker processes running as lower-privileged users, it is possible for the child processes to access memory shared with the main process and write to it, modifying it in a way that would cause the root process to conduct invalid memory reads and writes, which can be used to escalate privileges from local unprivileged user to the root user. En PHP versiones 7.3.x hasta 7.3.31 incluyéndola, versiones 7.4.x y por debajo de 7.4.25 y versiones 8.0.x por debajo de 8.0. 12, cuando es ejecutado PHP FPM SAPI con el proceso demonio FPM principal ejecutado como root y los procesos worker hijos ejecutados como usuarios menos privilegiados, es posible que los procesos hijos accedan a la memoria compartida con el proceso principal y escriban en ella, modificándola de forma que causaría que el proceso root realizara lecturas y escrituras de memoria no válidas, que puede ser usado para escalar los privilegios del usuario local sin privilegios al usuario root php-fpm has a vulnerability which may lead to local privilege escalation. This vulnerability is hard to exploit as the attack needs to escape the FPM sandbox mechanism. When a complete attack is achieved it may lead to risk for confidentiality, data integrity, and system availability. • http://www.openwall.com/lists/oss-security/2021/10/26/7 https://bugs.php.net/bug.php?id=81026 https://lists.debian.org/debian-lts-announce/2021/10/msg00021.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6PZVLICZUJMXOGWOUWSBAEGIVTF6Y6V3 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JO5RA6YOBGGGKLIA6F6BQRZDDECF5L3R https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PBM3KKB3RY2YPOKNMC4HIH7I • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-284: Improper Access Control CWE-787: Out-of-bounds Write •
