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.

The default configuration of Terminal in Apple Mac OS X 10.6 before 10.6.7 uses SSH protocol version 1 within the New Remote Connection dialog, which might make it easier for man-in-the-middle attackers to spoof SSH servers by leveraging protocol vulnerabilities.

QuickTime 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 crafted JPEG2000 image.

The plug-in in QuickTime in Apple Mac OS X before 10.6.7 allows remote attackers to bypass the Same Origin Policy and obtain potentially sensitive video data via vectors involving a cross-site redirect.

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.

Format string vulnerability in PackageKit in Apple Mac OS X 10.6.x before 10.6.6 allows man-in-the-middle attackers to execute arbitrary code or cause a denial of service (application crash) via vectors related to interaction between Software Update and distribution scripts.

QuickTime in Apple Mac OS X 10.6.x before 10.6.5 accesses uninitialized memory locations during processing of GIF image data, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted GIF file.

QuickLook in Apple Mac OS X 10.6.x before 10.6.5 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted Excel file.

Cross-site scripting (XSS) vulnerability in Wiki Server in Apple Mac OS X 10.5.8 and 10.6.x before 10.6.5 allows remote authenticated users to inject arbitrary web script or HTML via unspecified vectors.

QuickTime in Apple Mac OS X 10.6.x before 10.6.5 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted AVI file.
