Descriptions

Firejail before 0.9.44.6 and 0.9.38.x LTS before 0.9.38.10 LTS does not comprehensively address dotfile cases during its attempt to prevent accessing user files with an euid of zero, which allows local users to conduct sandbox-escape attacks via vectors involving a symlink and the --private option. NOTE: this vulnerability exists because of an incomplete fix for CVE-2017-5180.

Firejail en versiones anteriores a 0.9.44.6 y 0.9.38.x LTS en versiones anteriores a 0.9.38.10 LTS no aborda exhaustivamente los casos dotfile durante su intento de impedir el acceso a los archivos de usuario con un euid de cero, lo que permite a usuarios locales llevar a cabo ataques sybox-escape a través de vectores que implican un enlace simbólico y la opción --private. NOTA: esta vulnerabilidad existe debido a una solución incompleta para CVE-2017-5180.

Firejail is vulnerable to the escalation of privileges due to an incomplete fix for CVE-2017-5180. Versions less than 0.9.44.8 are affected.
