"value" : "An issue was discovered in LinuxTV xawtv before 3.107. The function dev_open() in v4l-conf.c does not perform sufficient checks to prevent an unprivileged caller of the program from opening unintended filesystem paths. This allows a local attacker with access to the v4l-conf setuid-root program to test for the existence of arbitrary files and to trigger an open on arbitrary files with mode O_RDWR. To achieve this, relative path components need to be added to the device path, as demonstrated by a v4l-conf -c /dev/../root/.bash_history command."

"value" : "Se detect\u00f3 un problema en LinuxTV xawtv versiones anteriores 3.107. La funci\u00f3n dev_open() en el archivo v4l-conf.c no realiza comprobaciones suficientes para evitar que un llamador sin privilegios del programa de apertura a rutas de sistema de archivos no deseadas. Esto permite a un atacante local con acceso al programa v4l-conf setuid-root probar la existencia de archivos arbitrarios y activar una apertura en archivos arbitrarios con el modo O_RDWR. Para lograr esto, los componentes de ruta relativa necesitan ser agregados a la ruta del dispositivo, como es demostrado por un comando v4l-conf -c /dev/../root/.bash_history"
