CVSS: 9.8EPSS: 1%CPEs: 11EXPL: 1CVE-2022-23219 – glibc: Stack-based buffer overflow in sunrpc clnt_create via a long pathname
https://notcve.org/view.php?id=CVE-2022-23219
The deprecated compatibility function clnt_create in the sunrpc module of the GNU C Library (aka glibc) through 2.34 copies its hostname argument on the stack without validating its length, which may result in a buffer overflow, potentially resulting in a denial of service or (if an application is not built with a stack protector enabled) arbitrary code execution. La función de compatibilidad obsoleta clnt_create en el módulo sunrpc de la Biblioteca C de GNU (también se conoce como glibc) versiones hasta 2.34, copia su argumento de nombre de host en la pila sin comprobar su longitud, que puede resultar en un desbordamiento de búfer, resultando potencialmente en una denegación de servicio o (si una aplicación no está construida con un protector de pila habilitado) la ejecución de código arbitrario A stack based buffer-overflow vulnerability was found in the deprecated compatibility function clnt_create() in the sunrpc's clnt_gen.c module of the GNU C Library (aka glibc) through 2.34. This vulnerability copies its hostname argument onto the stack without validating its length, which may result in a buffer overflow, potentially resulting in a denial of service or (if an application is not built with a stack protector enabled) lead to arbitrary code execution. • https://lists.debian.org/debian-lts-announce/2022/10/msg00021.html https://security.gentoo.org/glsa/202208-24 https://sourceware.org/bugzilla/show_bug.cgi?id=22542 https://www.oracle.com/security-alerts/cpujul2022.html https://access.redhat.com/security/cve/CVE-2022-23219 https://bugzilla.redhat.com/show_bug.cgi?id=2042017 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

https://notcve.org/view.php?id=CVE-2021-4083
A read-after-free memory flaw was found in the Linux kernel's garbage collection for Unix domain socket file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race condition. This flaw allows a local user to crash the system or escalate their privileges on the system. This flaw affects Linux kernel versions prior to 5.16-rc4. Se ha encontrado un fallo de lectura de memoria previamente liberada en la recolección de basura del kernel de Linux para los manejadores de archivos de socket de dominio Unix en la forma en que los usuarios llaman a close() y fget() simultáneamente y puede potencialmente desencadenar una condición de carrera. Este fallo permite a un usuario local bloquear el sistema o escalar sus privilegios en el sistema. • https://bugzilla.redhat.com/show_bug.cgi?id=2029923 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=054aa8d439b9 https://lists.debian.org/debian-lts-announce/2022/03/msg00011.html https://lists.debian.org/debian-lts-announce/2022/03/msg00012.html https://security.netapp.com/advisory/ntap-20220217-0005 https://www.debian.org/security/2022/dsa-5096 https://www.oracle.com/security-alerts/cpujul2022.html https://access.redhat.com/security/cve/CVE-202 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2021-42392
The org.h2.util.JdbcUtils.getConnection method of the H2 database takes as parameters the class name of the driver and URL of the database. An attacker may pass a JNDI driver name and a URL leading to a LDAP or RMI servers, causing remote code execution. This can be exploited through various attack vectors, most notably through the H2 Console which leads to unauthenticated remote code execution. El método org.h2.util.JdbcUtils.getConnection de la base de datos H2 toma como parámetros el nombre de la clase del controlador y la URL de la base de datos. Un atacante puede pasar un nombre de controlador JNDI y una URL que conlleve a un servidor LDAP o RMI, causando una ejecución de código remota. • https://github.com/cybersecurityworks553/CVE-2021-42392-Detect https://github.com/h2database/h2database/security/advisories/GHSA-h376-j262-vhq6 https://jfrog.com/blog/the-jndi-strikes-back-unauthenticated-rce-in-h2-database-console https://lists.debian.org/debian-lts-announce/2022/02/msg00017.html https://security.netapp.com/advisory/ntap-20220119-0001 https://www.debian.org/security/2022/dsa-5076 https://www.oracle.com/security-alerts/cpuapr2022.html https://www.secpod.com/blog/log4shell-critical • CWE-502: Deserialization of Untrusted Data •
