Overview
Affected versions of this package are vulnerable to Authentication Bypass Using an Alternate Path or Channel in the group_is_primary function. An attacker can gain unauthorized group privileges by exploiting certain mac_do rules that allow a process to set its primary group ID to the value of the first supplementary group, or to 0 (the "wheel" group) if the supplementary group list is empty. This is only exploitable if the attacker is able to apply a matching mac_do rule and the process has explicitly removed all supplementary groups using the privileged setgroups(2) system call. Depending on system configuration, this may allow further privilege escalation to root.
