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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Apple Safari before 5.1.1 on Mac OS X does not enforce an intended policy for file: URLs, which allows remote attackers to execute arbitrary code via a crafted web site.

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.

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.

Open Directory in Apple Mac OS X 10.7 before 10.7.2, when an LDAPv3 server is used with RFC 2307 or custom mappings, allows remote attackers to bypass the password requirement by leveraging lack of an AuthenticationAuthority attribute for a user account.

The SMB File Server component in Apple Mac OS X 10.7 before 10.7.2 does not prevent all guest users from accessing the share point record of a guest-restricted folder, which allows remote attackers to bypass intended browsing restrictions by leveraging access to the nobody account.

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.

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 FlashPix file.
