The Sorenson codec in QuickTime in Apple Mac OS X before 10.7.5, and in CoreMedia in iOS before 6, accesses uninitialized memory locations, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted movie file with Sorenson encoding.

Apple Mac OS X before 10.7.5 does not properly handle the bNbrPorts field of a USB hub descriptor, which allows physically proximate attackers to execute arbitrary code or cause a denial of service (memory corruption and system crash) by attaching a USB device.

Time Machine in Apple Mac OS X before 10.7.4 does not require continued use of SRP-based authentication after this authentication method is first used, which allows remote attackers to read Time Capsule credentials by spoofing the backup volume.

Buffer underflow in QuickTime in Apple Mac OS X before 10.7.4 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted MPEG file.

Integer overflow in QuickTime in Apple Mac OS X before 10.7.4 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted MPEG file.

Quartz Composer in Apple Mac OS X before 10.7.4, when the RSS Visualizer screensaver is enabled, allows physically proximate attackers to bypass screen locking and launch a Safari process via unspecified vectors.

Integer overflow in the Security Framework in Apple Mac OS X before 10.7.4 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via crafted input.

Buffer overflow in QuickTime in Apple Mac OS X before 10.7.4 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via crafted audio sample tables in a movie file that is progressively downloaded.

Race condition in the initialization routine in blued in Bluetooth in Apple Mac OS X before 10.7.4 allows local users to gain privileges via vectors involving a temporary file.

libsecurity in Apple Mac OS X before 10.7.4 does not properly restrict the length of RSA keys within X.509 certificates, which makes it easier for remote attackers to defeat cryptographic protection mechanisms by conducting a spoofing or network-sniffing attack during communication with a site that uses a short key.
