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.

libsecurity in Apple Mac OS X before 10.7.4 accesses uninitialized memory locations during the processing of X.509 certificates, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted certificate.

Apple Type Services (ATS) in Apple Mac OS X through 10.6.8 does not properly handle embedded Type 1 fonts, which allows remote attackers to execute arbitrary code via a crafted document that triggers an out-of-bounds memory access.

MediaKit in Apple Mac OS X through 10.6.8 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted disk image.

QuickTime in Apple Mac OS X before 10.7.2 does not properly handle the atom hierarchy in movie files, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted file.

QuickTime in Apple Mac OS X before 10.7.2 does not properly process URL data handlers in movie files, which allows remote attackers to obtain sensitive information from uninitialized memory locations via a crafted file.

The User Documentation component in Apple Mac OS X through 10.6.8 uses http sessions for updates to App Store help information, which allows man-in-the-middle attackers to execute arbitrary code by spoofing the http server.
