CVSS: 7.8EPSS: 0%CPEs: 1EXPL: 0CVE-2022-2319 – X.Org Server ProcXkbSetGeometry Out-Of-Bounds Access Local Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2022-2319
A flaw was found in the Xorg-x11-server. An out-of-bounds access issue can occur in the ProcXkbSetGeometry function due to improper validation of the request length. Se ha encontrado un fallo en Xorg-x11-server. Puede producirse un problema de acceso fuera de límites en la función ProcXkbSetGeometry debido a una comprobación inapropiada de la longitud de la petición This vulnerability allows local attackers to escalate privileges on affected installations of X.Org Server. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling of ProcXkbSetGeometry requests. • https://gitlab.freedesktop.org/xorg/xserver/-/merge_requests/938 https://gitlab.freedesktop.org/xorg/xserver/-/merge_requests/939 https://lists.freedesktop.org/archives/xorg-announce/2022-July/003192.html https://security.gentoo.org/glsa/202210-30 https://security.netapp.com/advisory/ntap-20221104-0003 https://www.zerodayinitiative.com/advisories/ZDI-22-964 https://access.redhat.com/security/cve/CVE-2022-2319 https://bugzilla.redhat.com/show_bug.cgi?id=2106671 • CWE-1320: Improper Protection for Outbound Error Messages and Alert Signals •

https://notcve.org/view.php?id=CVE-2022-2320
A flaw was found in the Xorg-x11-server. The specific flaw exists within the handling of ProcXkbSetDeviceInfo requests. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an allocated buffer. This flaw allows an attacker to escalate privileges and execute arbitrary code in the context of root.
