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.
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.
CFNetwork in Apple Mac OS X before 10.9 does not properly support Safari's deletion of session cookies in response to a reset operation, which makes it easier for remote web servers to track users via Set-Cookie HTTP headers.
Console in Apple Mac OS X before 10.9 allows user-assisted remote attackers to execute arbitrary applications by triggering a log entry with a crafted attached URL.
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.
Buffer underflow in CoreGraphics in Apple Mac OS X before 10.9 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted PDF document.
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.
The kernel in Apple Mac OS X before 10.9 does not properly determine the output length for SHA-2 digest function calls, which allows context-dependent attackers to cause a denial of service (panic) by triggering a digest operation, as demonstrated by an IPSec connection.
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.
