CVE-2005-0125
The "at" commands on Mac OS X 10.3.7 and earlier do not properly drop privileges, which allows local users to (1) delete arbitrary files via atrm, (2) execute arbitrary programs via the -f argument to batch, or (3) read arbitrary files via the -f argument to batch, which generates a job file that is readable by the local user.
