Descriptions

dmcrypt-get-device, as shipped in the eject package of Debian and Ubuntu, does not check the return value of the (1) setuid or (2) setgid function, which might cause dmcrypt-get-device to execute code, which was intended to run as an unprivileged user, as root. This affects eject through 2.1.5+deb1+cvs20081104-13.1 on Debian, eject before 2.1.5+deb1+cvs20081104-13.1ubuntu0.16.10.1 on Ubuntu 16.10, eject before 2.1.5+deb1+cvs20081104-13.1ubuntu0.16.04.1 on Ubuntu 16.04 LTS, eject before 2.1.5+deb1+cvs20081104-13.1ubuntu0.14.04.1 on Ubuntu 14.04 LTS, and eject before 2.1.5+deb1+cvs20081104-9ubuntu0.1 on Ubuntu 12.04 LTS.

Dispositivo dmcrypt-get_ , como se envía en el paquete de eyección de Debian y Ubuntu, no comprueba el valor devuelto de la (1) setuid o (2) la función setgid, lo que podría provocar que dmcrypt-get-device ejecute el código, que estaba destinado a ejecutarse como usuario no privilegiado, como root. Esto afecta expulsar hasta la versión 2.1.5 + deb1 + cvs20081104-13.1 en Debian, expulsar en versiones anteriores a 2.1.5 + deb1 + cvs20081104-13.1ubuntu0.16.10.1 en Ubuntu 16.10, expulsar en versiones anteriores a 2.1.5 + deb1 + cvs20081104-13.1ubuntu0 .16.04.1 en Ubuntu 16.04 LTS, expulsar en verisones anteriores a 2.1.5 + deb1 + cvs20081104-13.1ubuntu0.14.04.1 en Ubuntu 14.04 LTS, y expulsar en versiones anteriores a 2.1.5 + deb1 + cvs20081104-9ubuntu0.1 en Ubuntu 12.04 LTS.
