Directory Service in Apple Mac OS X through 10.6.8 allows remote attackers to execute arbitrary code or cause a denial of service (daemon crash) via a crafted message.

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 ZIPOPNOTIFY) packet that overwrites a certain ifPort structure member.

The NSURL component in Apple Mac OS X 10.4 through 10.4.10 performs case-sensitive comparisons that allow attackers to bypass intended restrictions for local file system URLs.

WebKit in Apple Mac OS X 10.3.9, 10.4.9 and later, and iPhone before 1.0.1 performs an "invalid type conversion", which allows remote attackers to execute arbitrary code via unspecified frame sets that trigger memory corruption.

Use-after-free vulnerability in Libinfo in Apple Mac OS X 10.3.9 through 10.4.9 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via unspecified vectors involving crafted web pages that trigger certain error conditions that are not properly reported in certain circumstances, resulting in accessing deallocated memory.

Heap-based buffer overflow in the VideoConference framework in Apple Mac OS X 10.3.9 through 10.4.9 allows remote attackers to execute arbitrary code via a "crafted SIP packet when initializing an audio/video conference".

Integer overflow in the RPC library in Libinfo in Apple Mac OS X 10.3.9 through 10.4.9 allows remote attackers to execute arbitrary code via crafted requests to portmap.

Stack-based buffer overflow in bootpd in the DHCP component for Apple Mac OS X 10.3.9 and 10.4.7 allows remote attackers to execute arbitrary code via a crafted BOOTP request.
