Vulnerability from fkie_nvd - Published: 2026-03-16 14:19 - Updated: 2026-03-17 18:59
Severity ?
7.8 (High) - CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Summary
GStreamer DVB Subtitles Out-Of-Bounds Write Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GStreamer. Interaction with this library is required to exploit this vulnerability but attack vectors may vary depending on the implementation. The specific flaw exists within the handling of coordinates. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28838.

Esta vulnerabilidad permite a atacantes remotos ejecutar c\u00f3digo arbitrario en instalaciones afectadas de GStreamer. Se requiere interacci\u00f3n con esta biblioteca para explotar esta vulnerabilidad, pero los vectores de ataque pueden variar dependiendo de la implementaci\u00f3n.\n\nLa falla espec\u00edfica reside en el manejo de coordenadas. El problema se debe a la falta de validaci\u00f3n adecuada de los datos proporcionados por el usuario, lo que puede resultar en una escritura m\u00e1s all\u00e1 del final de un b\u00fafer asignado. Un atacante puede aprovechar esta vulnerabilidad para ejecutar c\u00f3digo en el contexto del proceso actual. Fue ZDI-CAN-28838."
