Integer underflow in CoreGraphics in Apple Mac OS X 10.5 before 10.5.7, iPhone OS 1.0 through 2.2.1, and iPhone OS for iPod touch 1.1 through 2.2.1 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted PDF file that triggers a heap-based buffer overflow.

Launch Services in Apple Mac OS X 10.4.11 and 10.5 before 10.5.7 allows remote attackers to cause a denial of service (persistent Finder crash) via a crafted Mach-O executable that triggers an out-of-bounds memory read.

Apple Mac OS X 10.4.11 and 10.5 before 10.5.7 allows local users to gain privileges or cause a denial of service (application crash) by attempting to mount a crafted sparse disk image that triggers memory corruption.

Heap-based buffer overflow in CFNetwork in Apple Mac OS X 10.5 before 10.5.7 allows remote web servers to execute arbitrary code or cause a denial of service (application crash) via long HTTP headers.

The Microsoft Office Spotlight Importer in Spotlight in Apple Mac OS X 10.4.11 and 10.5 before 10.5.7 does not properly validate Microsoft Office files, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a file that triggers memory corruption.

Help Viewer in Apple Mac OS X 10.4.11 and 10.5 before 10.5.7 does not verify that certain Cascading Style Sheets (CSS) are located in a registered help book, which allows remote attackers to execute arbitrary code via a help: URL that triggers invocation of AppleScript files.

Array index error in the xnu (Mach) kernel in Apple Mac OS X 10.5 before 10.5.7 allows local users to gain privileges or cause a denial of service (system shutdown) via unspecified vectors related to workqueues.

XNU 1228.9.59 and earlier on Apple Mac OS X 10.5.6 and earlier does not properly restrict interaction between user space and the HFS IOCTL handler, which allows local users to overwrite kernel memory and gain privileges by attaching an HFS+ disk image and performing certain steps involving HFS_GET_BOOT_INFO fcntl calls.

Heap-based buffer overflow in the AppleTalk networking stack in XNU 1228.3.13 and earlier on Apple Mac OS X 10.5.6 and earlier allows remote attackers to cause a denial of service (system crash) via a ZIP NOTIFY (aka ZIPOP_NOTIFY) packet that overwrites a certain ifPort structure member.

Race condition in the HFS vfs sysctl interface in XNU 1228.8.20 and earlier on Apple Mac OS X 10.5.6 and earlier allows local users to cause a denial of service (kernel memory corruption) by simultaneously executing the same HFS_SET_PKG_EXTENSIONS code path in multiple threads, which is problematic because of lack of mutex locking for an unspecified global variable.
