Mobile Accounts in Apple Mac OS X before 10.7.5 and 10.8.x before 10.8.2 saves password hashes for external-account use even if external accounts are not enabled, which might allow remote attackers to determine passwords via unspecified access to a mobile account.

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.

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.
