Mail in Apple Mac OS X before 10.9 allows remote attackers to spoof the existence of a cryptographic signature for an e-mail message by using the multipart/signed content type within an unsigned message.
Mail in Apple Mac OS X before 10.9, when Kerberos authentication is enabled and TLS is disabled, sends invalid cleartext data, which allows remote attackers to obtain sensitive information by sniffing the network.
The kernel in Apple Mac OS X before 10.9 does not properly check for errors during the processing of multicast Wi-Fi packets, which allows remote attackers to cause a denial of service (system crash) by leveraging presence in an 802.11 network's coverage area.
The ldapsearch command-line program in OpenLDAP in Apple Mac OS X before 10.9 does not properly process the minssf configuration setting, which allows remote attackers to obtain sensitive information by leveraging unintended weak encryption and sniffing the network.
Power Management in Apple Mac OS X before 10.9 does not properly handle the interaction between locking and power assertions, which allows physically proximate attackers to obtain sensitive information by reading a screen that should have transitioned into the locked state.
The Screen Lock implementation in Apple Mac OS X before 10.9 does not immediately accept Keychain Status menu Lock Screen commands, and instead incorrectly relies on a certain timeout setting, which allows physically proximate attackers to obtain sensitive information by reading a screen that should have transitioned into the locked state.
The Screen Lock implementation in Apple Mac OS X before 10.9, when hibernation and autologin are enabled, does not require a password for a transition out of hibernation, which allows physically proximate attackers to obtain access by visiting an unattended workstation in the hibernating state.
Apple Mac OS X before 10.9 does not preserve a certain administrative system-preferences setting across software updates, which allows context-dependent attackers to bypass intended access restrictions in opportunistic circumstances by leveraging an unintended security configuration after the completion of an update.
Smart Card Services in Apple Mac OS X before 10.9 does not properly implement certificate-revocation checks, which allows remote attackers to cause a denial of service (Smart Card usage outage) by interfering with the revocation-check procedure.
The syslog implementation in Apple Mac OS X before 10.9 allows local users to obtain sensitive information by leveraging access to the Guest account and reading console-log messages from previous Guest sessions.
