Stack-based buffer overflow in the VPN daemon (vpnd) for Mac OS X before 10.3.9 allows local users to execute arbitrary code via a long -i (Server_id) argument.

Mac OS X 10.3.x and earlier uses insecure permissions for a pseudo terminal tty (pty) that is managed by a non-setuid program, which allows local users to read or modify sessions of other users.

Mac OS X 10.3.9 and earlier allows users to install, create, and execute setuid/setgid scripts, contrary to the intended design, which may allow attackers to conduct unauthorized activities with escalated privileges via vulnerable scripts.

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.

Integer overflow in the TIFFFetchStripThing function in tif_dirread.c for libtiff 3.6.1 allows remote attackers to execute arbitrary code via a TIFF file with the STRIPOFFSETS flag and a large number of strips, which causes a zero byte buffer to be allocated and leads to a heap-based buffer overflow.

Buffer overflow in TruBlueEnvironment in Mac OS X 10.3.x and 10.2.x allows local users to gain privileges via a long environment variable.
