Buffer overflow in the ATSFontDeactivate API in Apple Type Services (ATS) in Apple Mac OS X before 10.7.2 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via unspecified vectors.

CoreMedia in Apple Mac OS X through 10.6.8 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted QuickTime movie file.

Buffer overflow in QuickTime in Apple Mac OS X before 10.7.2 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted FLIC movie file.

The kernel in Apple Mac OS X before 10.7.2 does not properly prevent FireWire DMA in the absence of a login, which allows physically proximate attackers to bypass intended access restrictions and discover a password by making a DMA request in the (1) loginwindow, (2) boot, or (3) shutdown state.

QuickTime in Apple Mac OS X before 10.7.2 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted movie file.

The "Save for Web" selection in QuickTime Player in Apple Mac OS X through 10.6.8 exports HTML documents that contain an http link to a script file, which allows man-in-the-middle attackers to conduct cross-site scripting (XSS) attacks by spoofing the http server during local viewing of an exported document.

The kernel in Apple Mac OS X before 10.7.2 does not properly implement the sticky bit for directories, which might allow local users to bypass intended permissions and delete files via an unlink system call.

CFNetwork in Apple Mac OS X before 10.7.2 does not properly follow an intended cookie-storage policy, which makes it easier for remote web servers to track users via a cookie, related to a "synchronization issue."

libsecurity in Apple Mac OS X before 10.7.2 does not properly handle errors during processing of a nonstandard extension in a Certificate Revocation list (CRL), which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) a crafted (1) web site or (2) e-mail message.

IOGraphics in Apple Mac OS X through 10.6.8 does not properly handle a locked-screen state in display sleep mode for an Apple Cinema Display, which allows physically proximate attackers to bypass the password requirement via unspecified vectors.
