Description
KisMAC before 0.05d trusts user-supplied variables when chown'ing files or directories, which allows local users to gain privileges via the $DRIVER_KEXT environment variable in (1) viha_driver.sh, (2) macjack_load.sh, (3) airojack_load.sh, (4) setuid_enable.sh, (5) setuid_disable.sh, and using a "similar technique" for (6) viha_prep.sh and (7) viha_unprep.sh.
