NetFS Client Framework in Apple OS X before 10.10 does not ensure that the disabling of File Sharing is always possible, which allows remote attackers to read or write to files by leveraging a state in which File Sharing is permanently enabled.

CFPreferences in Apple OS X before 10.10 does not properly enforce the “require password after sleep or screen saver begins” setting, which makes it easier for physically proximate attackers to obtain access by leveraging an unattended workstation.

Apple OS X before 10.10 allows remote attackers to cause a denial of service (NULL pointer dereference) via crafted ASN.1 data.

Buffer overflow in QuickTime in Apple OS X before 10.10 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via crafted audio samples in an m4a file.

Bluetooth in Apple OS X before 10.10 does not require encryption for HID Low Energy devices, which allows remote attackers to spoof a device by leveraging previous pairing.

Mail in Apple OS X before 10.10 does not properly recognize the removal of a recipient address from a message, which makes it easier for remote attackers to obtain sensitive information in opportunistic circumstances by reading a message intended exclusively for other recipients.

CoreStorage in Apple OS X before 10.10 retains a volume’s encryption keys upon an eject action in the unlocked state, which makes it easier for physically proximate attackers to obtain cleartext data via a remount.

The kernel in Apple OS X before 10.10 allows local users to cause a denial of service (panic) via a message to a system control socket.

The Code Signing feature in Apple OS X before 10.10 does not properly handle incomplete resource envelopes in signed bundles, which allows remote attackers to bypass intended app-author restrictions by omitting an execution-related resource.
