Description

opiepasswd contains a flaw that may allow a malicious user to gain access to unauthorized privileges. The issue is triggered when opiepasswd uses getlogin(2) to identify the user who called opiepasswd. Under certain circumstances getlogin(2) will return user "root" even when running as an unprivileged user. This flaw may lead to a loss of integrity.
