Integer underflow in QuickDraw Manager in Apple Mac OS X 10.4.11 and 10.5 before 10.5.7, and Apple QuickTime before 7.6.2, allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a PICT image with a crafted 0x77 Poly tag and a crafted length field, which triggers a heap-based buffer overflow.

Stack-based buffer overflow in telnet in Apple Mac OS X 10.4.11 and 10.5 before 10.5.7 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a long hostname for a telnet server.

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.

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.

Multiple integer overflows in FreeType 2.3.9 and earlier allow remote attackers to execute arbitrary code via vectors related to large values in certain inputs in (1) smooth/ftsmooth.c, (2) sfnt/ttcmap.c, and (3) cff/cffload.c.

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.

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.

Multiple memory leaks in XNU 1228.3.13 and earlier on Apple Mac OS X 10.5.6 and earlier allow local users to cause a denial of service (kernel memory consumption) via a crafted (1) SYS_add_profil or (2) SYS___mac_getfsstat system call.
