Description
A bug exists in the polkit pkexec binary in how it processes arguments. If
the binary is provided with no arguments, it will continue to process environment
variables as argument variables, but without any security checking.
By using the execve call we can specify a null argument list and populate the
proper environment variables. This exploit is architecture independent.
