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.
Mail in Mac OS X 10.3.7, when generating a Message-ID header, generates a GUUID that includes information that identifies the Ethernet hardware being used, which allows remote attackers to link mail messages to a particular machine.
The Finder in Mac OS X and earlier allows local users to overwrite arbitrary files and gain privileges by creating a hard link from the .DS_Store file to an arbitrary file.
Integer signedness error in the parse_machfile function in the mach-o loader (mach_loader.c) for the Darwin Kernel as used in Mac OS X 10.3.7, and other versions before 10.3.9, allows local users to cause a denial of service (CPU consumption) via a crafted mach-o header.
exif.c in PHP before 4.3.11 allows remote attackers to cause a denial of service (memory consumption and crash) via an EXIF header with a large IFD nesting level, which causes significant stack recursion.
The Bluetooth Setup Assistant for Mac OS X before 10.3.8 can be launched without a keyboard or Bluetooth device, which allows local users to bypass access restrictions and gain privileges.
Stack-based buffer overflow in the Core Foundation Library in Mac OS X 10.3.5 and 10.3.6, and possibly earlier versions, allows local users to execute arbitrary code via a long CF_CHARSET_PATH environment variable.
Multiple integer overflows in libtiff 3.6.1 and earlier allow remote attackers to cause a denial of service (crash or memory corruption) via TIFF images that lead to incorrect malloc calls.
