Descriptions
A flaw was found in xorg-server. Querying or changing XKB button actions such as moving from a touchpad to a mouse can result in out-of-bounds memory reads and writes. This may allow local privilege escalation or possible remote code execution in cases where X11 forwarding is involved.
Se encontró una falla en xorg-server. Consultar o cambiar las acciones de los botones XKB, como pasar de un panel táctil a un mouse, puede provocar lecturas y escrituras de memoria fuera de los límites. Esto puede permitir una escalada de privilegios local o una posible ejecución remota de código en los casos en que esté involucrado el reenvío X11.
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 Button Action objects. 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. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of root.
