The scan function in ext/date/lib/parse_iso_intervals.c in PHP through 5.5.6 does not properly restrict creation of DateInterval objects, which might allow remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted interval specification.

The USB hub controller in Apple Mac OS X before 10.9 allows local users to cause a denial of service (system crash) via a request with a crafted (1) port or (2) port number.

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.

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.

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.

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.

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.

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 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.

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.

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.

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.

The auto-configuration feature in Mail in Apple Mac OS X before 10.9 selects plaintext authentication for unspecified servers that support CRAM-MD5 authentication, which allows remote attackers to obtain sensitive information by sniffing the network.

The srandomdev function in Libc in Apple Mac OS X before 10.9, when the kernel random-number generator is unavailable, produces predictable values instead of the intended random values, which makes it easier for context-dependent attackers to defeat cryptographic protection mechanisms by leveraging knowledge of these values, related to a compiler-optimization issue.

App Sandbox in Apple Mac OS X before 10.9 allows attackers to bypass intended sandbox restrictions via a crafted app that uses the LaunchServices interface to specify process arguments.

LaunchServices in Apple Mac OS X before 10.9 does not properly restrict Unicode characters in filenames, which allows context-dependent attackers to spoof file extensions via a crafted character sequence.

The kernel in Apple Mac OS X before 10.9 allows local users to cause a denial of service (panic) via an invalid iovec structure.

The kernel in Apple Mac OS X before 10.9 does not properly handle integer values during unspecified tty device operations, which allows local users to cause a denial of service (system hang) by triggering a truncation error.

The kernel in Apple Mac OS X before 10.9 allows local users to obtain sensitive information or cause a denial of service (out-of-bounds read and system crash) via a crafted Mach-O file.

Integer signedness error in the kernel in Apple Mac OS X before 10.9 allows local users to cause a denial of service (system crash) via a crafted tty read operation.
