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.

csregprinter in the Printing component in Apple Mac OS X 10.4.11 and 10.5.6 does not properly handle error conditions, which allows local users to execute arbitrary code via unknown vectors that trigger a heap-based buffer overflow.

dscl in DS Tools in Apple Mac OS X 10.4.11 and 10.5.6 requires that passwords must be provided as command line arguments, which allows local users to gain privileges by listing process information.

XTerm in Apple Mac OS X 10.4.11 and 10.5.6, when used with luit, creates tty devices with insecure world-writable permissions, which allows local users to write to the Xterm of another user.

Unspecified vulnerability in the Pixlet codec in Apple Mac OS X 10.4.11 and 10.5.6 allows remote attackers to cause a denial of service (application termination) and possibly execute arbitrary code via a crafted movie file that triggers memory corruption.

Remote Apple Events in Apple Mac OS X 10.4.11 and 10.5.6 allows remote attackers to cause a denial of service (application termination) or obtain sensitive information via unspecified vectors that trigger an out-of-bounds memory access.

Unspecified vulnerability in CarbonCore in Apple Mac OS X 10.4.11 and 10.5.6 allows remote attackers to cause a denial of service (application termination) and execute arbitrary code via a crafted resource fork that triggers memory corruption.

The Remote Apple Events server in Apple Mac OS X 10.4.11 and 10.5.6 does not properly initialize a buffer, which allows remote attackers to read portions of memory.

Unspecified vulnerability in the SMB component in Apple Mac OS X 10.4.11 and 10.5.6 allows remote SMB servers to cause a denial of service (memory exhaustion and system shutdown) via a crafted file system name.

Integer overflow in the inet_net_pton API in Libsystem in Apple Mac OS X before 10.5.6 allows context-dependent attackers to execute arbitrary code or cause a denial of service (application crash) via unspecified vectors. NOTE: this may be related to the WLB-2008080064 advisory published by SecurityReason on 20080822; however, as of 20081216, there are insufficient details to be sure.
