https://notcve.org/view.php?id=CVE-2022-4144
An out-of-bounds read flaw was found in the QXL display device emulation in QEMU. The qxl_phys2virt() function does not check the size of the structure pointed to by the guest physical address, potentially reading past the end of the bar space into adjacent pages. A malicious guest user could use this flaw to crash the QEMU process on the host causing a denial of service condition. Se encontró una falla de lectura fuera de los límites en la emulación del dispositivo de visualización QXL en QEMU. La función qxl_phys2virt() no verifica el tamaño de la estructura a la que apunta la dirección física del invitado, lo que potencialmente lee más allá del final del espacio de la barra en páginas adyacentes. • https://bugzilla.redhat.com/show_bug.cgi?id=2148506 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GTVPHLLXJ65BUMFBUUZ35F3J632SLFRK https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/I7J5IRXJYLELW7D43A75LOWRUE5EU54O https://lists.nongnu.org/archive/html/qemu-devel/2022-11/msg04143.html https://security.netapp.com/advisory/ntap-20230127-0012 https://access.redhat.com/security/cve/CVE-2022-4144 • CWE-125: Out-of-bounds Read •

A flaw was found in the Linux kernel's Layer 2 Tunneling Protocol (L2TP). A missing lock when clearing sk_user_data can lead to a race condition and NULL pointer dereference. A local user could use this flaw to potentially crash the system causing a denial of service. Se encontró una falla en Layer 2 Tunneling Protocol (L2TP) del kernel de Linux.

CVSS: 7.8EPSS: 0%CPEs: 5EXPL: 0CVE-2022-45939 – emacs: ctags local command execution vulnerability
https://notcve.org/view.php?id=CVE-2022-45939
GNU Emacs through 28.2 allows attackers to execute commands via shell metacharacters in the name of a source-code file, because lib-src/etags.c uses the system C library function in its implementation of the ctags program. For example, a victim may use the "ctags *" command (suggested in the ctags documentation) in a situation where the current working directory has contents that depend on untrusted input. GNU Emacs hasta la versión 28.2 permite a los atacantes ejecutar comandos a través de metacaracteres de shell en el nombre de un archivo de código fuente, porque lib-src/etags.c utiliza la función de librería C del sistema en su implementación del programa ctags. Por ejemplo, una víctima puede utilizar el comando "ctags *" (sugerido en la documentación de ctags) en una situación en la que el directorio de trabajo actual tiene contenidos que dependen de entradas que no son de confianza. A flaw was found in Etags, the Ctags implementation of Emacs. • https://git.savannah.gnu.org/cgit/emacs.git/commit/?id=d48bb4874bc6cd3e69c7a15fc3c91cc141025c51 https://lists.debian.org/debian-lts-announce/2022/12/msg00046.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FOSK3J7BBAEI4IITW2DRUKLQYUZYKH6Y https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GOXIH2FDEQJEAARE52C3GHTLGQFBYPIB https://www.debian.org/security/2023/dsa-5314 https://access.redhat.com/security/cve/CVE-2022-45939 https://bugzill • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •

https://notcve.org/view.php?id=CVE-2022-45152
A blind Server-Side Request Forgery (SSRF) vulnerability was found in Moodle. This flaw exists due to insufficient validation of user-supplied input in LTI provider library. The library does not utilise Moodle's inbuilt cURL helper, which resulted in a blind SSRF risk. An attacker can send a specially crafted HTTP request and trick the application to initiate requests to arbitrary systems. This vulnerability allows a remote attacker to perform SSRF attacks. • http://git.moodle.org/gw?p=moodle.git&a=search&h=HEAD&st=commit&s=MDL-71920 https://bugzilla.redhat.com/show_bug.cgi?id=2142775 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/2DHYIIAUXUBHMBEDYU7TYNZXEN2W2SA2 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/74SXNGA5RIWM7QNX7H3G7SYIQLP4UUGV https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/NLRJB5JNKK3VVBLV3NH3RI7COEDAXSAB https://moodle.org/mod/foru • CWE-918: Server-Side Request Forgery (SSRF) •
