CVE-2021-31578

Estado: ModificadaCrítica (9.8)—

In Boa, there is a possible escalation of privilege due to a stack buffer overflow. This could lead to remote escalation of privilege from a proximal attacker with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: A20210008; Issue ID: OSBNB00123241.
