Descriptions

The bzexe command in bzip2 1.0.5 and earlier generates compressed executables that do not properly handle temporary files during extraction, which allows local users to execute arbitrary code by precreating a temporary directory.

El comando bzexe en bzip2 1.0.5 y anteriores genera ejecutables comprimidos que no manejan debidamente archivos temporales durante extracción, lo que permite a usuarios locales ejecutar código arbitrario mediante la precreación de un directorio temporal.

bzexe suffers from a /tmp race condition that allows for local root compromise.
