The Private Browsing feature in Apple Safari before 5.1.1 on Mac OS X does not properly recognize the Always value of the Block Cookies setting, which makes it easier for remote web servers to track users via a cookie.

CFNetwork in Apple iOS before 5.0.1 and Mac OS X 10.7 before 10.7.2 does not properly parse URLs, which allows remote attackers to trigger visits to unintended web sites, and transmission of cookies to unintended web sites, via a crafted (1) http or (2) https URL.

Open Directory in Apple Mac OS X 10.7 before 10.7.2 allows local users to read the password data of arbitrary users via unspecified vectors.

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.

Open Directory in Apple Mac OS X 10.7 before 10.7.2 does not require a user to provide the current password before changing this password, which allows remote attackers to bypass intended password-change restrictions by leveraging an unattended workstation.

Integer signedness error in Apple Type Services (ATS) in Apple Mac OS X 10.7 before 10.7.2 allows remote attackers to execute arbitrary code via a crafted embedded Type 1 font in a document.

Address Book in Apple Mac OS X before 10.7.3 automatically switches to unencrypted sessions upon failure of encrypted connections, which allows remote attackers to read CardDAV data by terminating an encrypted connection and then sniffing the network.

Apple Type Services (ATS) in Apple Mac OS X before 10.7.3 does not properly manage memory for data-font files, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted font that is accessed by Font Book.

CFNetwork in Apple Mac OS X 10.7.x before 10.7.3 does not properly construct request headers during parsing of URLs, which allows remote attackers to obtain sensitive information via a malformed URL.

Heap-based buffer overflow in CoreMedia in Apple Mac OS X before 10.7.3 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted movie file with H.264 encoding.

Use-after-free vulnerability in CoreText in Apple Mac OS X before 10.7.3 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted embedded font in a document.

CoreUI in Apple Mac OS X 10.7.x before 10.7.3 does not properly restrict the allocation of stack memory, which allows remote attackers to execute arbitrary code or cause a denial of service (memory consumption and application crash) via a long URL.

Internet Sharing in Apple Mac OS X before 10.7.3 does not preserve the Wi-Fi configuration across software updates, which allows remote attackers to obtain sensitive information by leveraging the lack of a WEP password for a Wi-Fi network.

Integer overflow in libresolv in Apple Mac OS X before 10.7.3 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption and application crash) via crafted DNS data.

The OpenGL implementation in Apple Mac OS X before 10.7.3 does not properly perform OpenGL Shading Language (aka GLSL) compilation, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted program.

QuickTime in Apple Mac OS X before 10.7.3 does not prevent access to uninitialized memory locations, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted MP4 file.

Off-by-one error in QuickTime in Apple Mac OS X before 10.7.3 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted rdrf atom in a movie file that triggers a buffer overflow.

Buffer overflow in QuickTime in Apple Mac OS X before 10.7.3 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted PNG file.

Time Machine in Apple Mac OS X before 10.7.3 does not verify the unique identifier of its remote AFP volume or Time Capsule, which allows remote attackers to obtain sensitive information contained in new backups by spoofing this storage object, a different vulnerability than CVE-2010-1803.

WebDAV Sharing in Apple Mac OS X 10.7.x before 10.7.3 does not properly perform authentication, which allows local users to gain privileges by leveraging access to (1) the server or (2) a bound directory.
