Descriptions

libcue provides an API for parsing and extracting data from CUE sheets. Versions 2.2.1 and prior are vulnerable to out-of-bounds array access. A user of the GNOME desktop environment can be exploited by downloading a cue sheet from a malicious webpage. Because the file is saved to `~/Downloads`, it is then automatically scanned by tracker-miners. And because it has a .cue filename extension, tracker-miners use libcue to parse the file. The file exploits the vulnerability in libcue to gain code execution. This issue is patched in version 2.3.0.

libcue proporciona una API para analizar y extraer datos de hojas CUE. Las versiones 2.2.1 y anteriores son vulnerables al acceso a matrices fuera de los límites. Un usuario del entorno de escritorio GNOME puede ser explotado descargando una hoja CUE de una página web maliciosa. Debido a que el archivo se guarda en `~/Downloads`, los tracker-miners lo escanean automáticamente. Y debido a que tiene una extensión de nombre de archivo .cue, los tracker-miners usan libcue para analizar el archivo. El archivo explota la vulnerabilidad en libcue para obtener la ejecución del código. Este problema se solucionó en la versión 2.3.0.
