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.

The File Systems component in Apple Mac OS X before 10.7.2 does not properly track the specific X.509 certificate that a user manually accepted for an initial https WebDAV connection, which allows man-in-the-middle attackers to hijack WebDAV communication by presenting an arbitrary certificate for a subsequent connection.

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."

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.

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.

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.

Format string vulnerability in the debug-logging feature in Application Firewall in Apple Mac OS X before 10.7.2 allows local users to gain privileges via a crafted name of an executable file.

The Keychain implementation in Apple Mac OS X 10.6.8 and earlier does not properly handle an untrusted attribute of a Certification Authority certificate, which makes it easier for man-in-the-middle attackers to spoof arbitrary SSL servers via an Extended Validation certificate, as demonstrated by https access with Safari.

Libinfo in Apple Mac OS X before 10.6.7 does not properly handle an unspecified integer field in an NFS RPC packet, which allows remote attackers to cause a denial of service (lockd, statd, mountd, or portmap outage) via a crafted packet, related to an "integer truncation issue."

The i386_set_ldt system call in the kernel in Apple Mac OS X before 10.6.7 does not properly handle call gates, which allows local users to gain privileges via vectors involving the creation of a call gate entry.

Integer overflow in ImageIO in Apple Mac OS X before 10.6.7 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted XBM image.

Integer overflow in HFS in Apple Mac OS X before 10.6.7 allows local users to read arbitrary (1) HFS, (2) HFS+, or (3) HFS+J files via a crafted F_READBOOTSTRAP ioctl call.

CoreText in Apple Mac OS X before 10.6.7 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a document that contains a crafted embedded font.

The FSFindFolder API in CarbonCore in Apple Mac OS X before 10.6.7 provides a world-readable directory in response to a call with the kTemporaryFolderType flag, which allows local users to obtain potentially sensitive information by accessing this directory.

Multiple buffer overflows in Apple Type Services (ATS) in Apple Mac OS X before 10.6.7 allow remote attackers to execute arbitrary code via a document that contains a crafted SFNT table in an embedded font.

Multiple buffer overflows in Apple Type Services (ATS) in Apple Mac OS X before 10.6.7 allow remote attackers to execute arbitrary code via a document that contains a crafted embedded Type 1 font.

Multiple buffer overflows in Apple Type Services (ATS) in Apple Mac OS X before 10.6.7 allow remote attackers to execute arbitrary code via a document that contains a crafted embedded TrueType font.

Heap-based buffer overflow in Apple Type Services (ATS) in Apple Mac OS X before 10.6.7 allows remote attackers to execute arbitrary code via a document that contains a crafted embedded OpenType font.

Multiple format string vulnerabilities in AppleScript in Apple Mac OS X before 10.6.7 allow context-dependent attackers to execute arbitrary code or cause a denial of service (application crash) via format string specifiers in a (1) display dialog or (2) display alert command in a dialog in an AppleScript Studio application.

Integer overflow in QuickLook, as used in Apple Mac OS X before 10.6.7 and MobileSafari in Apple iOS before 4.2.7 and 4.3.x before 4.3.2, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a Microsoft Office document with a crafted size field in the OfficeArtMetafileHeader, related to OfficeArtBlip, as demonstrated on the iPhone by Charlie Miller and Dion Blazakis during a Pwn2Own competition at CanSecWest 2011.
