Descriptions

Firejail before 0.9.44.4 and 0.9.38.x LTS before 0.9.38.8 LTS does not consider the .Xauthority case 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.

Firejail en versiones anteriores a 0.9.44.4 y 0.9.38.x LTS en versiones anteriores a 0.9.38.8 LTS no considera el caso .Xauthority durante su intento para impedir el acceso a los archivos de usuario con un euid de cero, lo que permite a usuarios locales llevar a cabo ataques de sybox-escape a través de vectores que implican un enlace simbólico y la opción --private.

Multiple vulnerabilities have been discovered in Firejail, the worst of which may allow privilege escalation. Versions less than 0.9.44.4 are affected.
