Apple Mac OS X 10.8.3

The mach_port_space_info function in osfmk/ipc/mach_debug.c in the XNU kernel in Apple Mac OS X 10.8.x does not initialize a certain structure member, which allows local users to obtain sensitive information from kernel heap memory via a crafted call.

The Bluetooth USB host controller in Apple Mac OS X before 10.9 prematurely deletes interfaces, which allows local users to cause a denial of service (system crash) via a crafted application.

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 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.

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.

sys/openbsd/stack_protector.c in libc in Apple iOS 6.1.3 and Mac OS X 10.8.x does not properly parse the Apple strings employed in the user-space stack-cookie implementation, which allows local users to bypass cookie randomization by executing a program with a call-path beginning with the stack-guard= substring, as demonstrated by an iOS untethering attack or an attack against a setuid Mac OS X program.

The systemsetup program in the Date and Time subsystem in Apple OS X before 10.9.2 allows local users to bypass intended access restrictions by changing the current time on the system clock.

CFNetwork in Apple iOS before 7.1.1, Apple OS X through 10.9.2, and Apple TV before 6.1.1 does not ensure that a Set-Cookie HTTP header is complete before interpreting the header's value, which allows remote attackers to bypass intended access restrictions by triggering the closing of a TCP connection during transmission of a header, as demonstrated by an HTTPOnly restriction.

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.

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 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 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.

CFNetwork in Apple OS X through 10.8.5 does not remove session cookies upon a Safari reset action, which allows physically proximate attackers to bypass intended access restrictions by leveraging an unattended workstation.

Power Management in Apple Mac OS X before 10.8.5 does not properly perform locking upon occurrences of a power assertion, which allows physically proximate attackers to bypass intended access restrictions by visiting an unattended workstation on which a locking failure had prevented the startup of the screen saver.

CoreGraphics in Apple Mac OS X before 10.9 allows local users to bypass secure input mode and log an arbitrary application's keystrokes via a hotkey event registration.

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 posix_spawn system call in the XNU kernel in Apple Mac OS X 10.8.x does not prevent use of the _POSIX_SPAWN_DISABLE_ASLR and _POSIX_SPAWN_ALLOW_DATA_EXEC flags for setuid and setgid programs, which allows local users to bypass intended access restrictions via a wrapper program that calls the posix_spawnattr_setflags function.

CFNetwork in Apple iOS before 8.1.1 and OS X before 10.10.1 does not properly clear the browsing cache upon a transition out of private-browsing mode, which makes it easier for physically proximate attackers to obtain sensitive information by reading cache files.

The fill_pipeinfo function in bsd/kern/sys_pipe.c in the XNU kernel in Apple Mac OS X 10.8.x allows local users to defeat the KASLR protection mechanism via the PROC_PIDFDPIPEINFO option to the proc_info system call for a kernel pipe handle.

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 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.

mdmclient in Mobile Device Management in Apple Mac OS X before 10.8.5 places a password on the command line, which allows local users to obtain sensitive information by listing the process.

The random-number generator in the kernel in Apple Mac OS X before 10.9 provides lengthy exclusive access for processing of large requests, which allows local users to cause a denial of service (temporary generator outage) via an application that requires many random numbers.

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.

CoreGraphics in Apple Mac OS X before 10.9, when display-sleep mode is used, does not ensure that screen locking blocks the visibility of all windows, which allows physically proximate attackers to obtain sensitive information by reading the screen.
