Mac OS X before 10.3 with core files enabled allows local users to overwrite arbitrary files and read core files via a symlink attack on core files that are created with predictable names in the /cores directory.

Finder in Mac OS X 10.2.8 and earlier sets global read/write/execute permissions on directories when they are dragged (copied) from a mounted volume such as a disk image (DMG), which could cause the directories to have less restrictive permissions than intended.

DirectoryServices in MacOS X trusts the PATH environment variable to locate and execute the touch command, which allows local users to execute arbitrary commands by modifying the PATH to point to a directory containing a malicious touch program.

Mac OS X before 10.2.5 allows guest users to modify the permissions of the DropBox folder and read unauthorized files.

The default configuration of Mail.app in Mac OS X 10.0 through 10.0.4 and 10.1 through 10.1.5 sends iDisk authentication credentials in cleartext when connecting to Mac.com, which could allow remote attackers to obtain passwords by sniffing network traffic.

The Sun RPC functionality in multiple libc implementations does not provide a time-out mechanism when reading data from TCP connections, which allows remote attackers to cause a denial of service (hang).

The ASN1 library in OpenSSL 0.9.6d and earlier, and 0.9.7-beta2 and earlier, allows remote attackers to cause a denial of service via invalid encodings.

Buffer overflows in OpenSSL 0.9.6d and earlier, and 0.9.7-beta2 and earlier, allow remote attackers to execute arbitrary code via (1) a large client master key in SSL2 or (2) a large session ID in SSL3.

OpenSSL 0.9.6d and earlier, and 0.9.7-beta2 and earlier, does not properly handle ASCII representations of integers on 64 bit platforms, which could allow attackers to cause a denial of service and possibly execute arbitrary code.

SoftwareUpdate for MacOS 10.1.x does not use authentication when downloading a software update, which could allow remote attackers to execute arbitrary code by posing as the Apple update server via techniques such as DNS spoofing or cache poisoning, and supplying Trojan Horse updates.
