Descriptions

Sudo before 1.9.15 might allow row hammer attacks (for authentication bypass or privilege escalation) because application logic sometimes is based on not equaling an error value (instead of equaling a success value), and because the values do not resist flips of a single bit.

Sudo anterior a 1.9.15 podría permitir row hammer attacks (para eludir la autenticación o escalar privilegios) porque la lógica de la aplicación a veces se basa en no igualar un valor de error (en lugar de igualar un valor de éxito) y porque los valores no resisten los cambios de un solo bit.

A flaw was found in the sudo package. This issue could allow a local authenticated attacker to cause a bit to flip, which enables fault injection and may authenticate as the root user.
