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 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 kSBXProfileNoNetwork and kSBXProfileNoInternet sandbox profiles in Apple Mac OS X 10.5.x through 10.7.x do not propagate restrictions to all created processes, which allows remote attackers to access network resources via a crafted application, as demonstrated by use of osascript to send Apple events to the launchd daemon, a related issue to CVE-2008-7303.

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 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.

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.

The CoreProcesses component in Apple Mac OS X 10.7 before 10.7.2 does not prevent a system window from receiving keystrokes in the locked-screen state, which might allow physically proximate attackers to bypass intended access restrictions by typing into this window.

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, 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.

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.
