Apple Mac OS X CoreGraphics Quartz Event Services security bypass

macos-coregraphics-quartz-security-bypass (26409) The risk level is classified as LowLow Risk


Apple Mac OS X and Mac OS X Server could provide weaker than expected security, caused by a vulnerability in the Quartz Event Services CoreGraphics module. If the "Enable access for assistive devices" option is turned on, Quartz Event Services could intercept events even if secure event input is enabled. This could allow a local attacker to obtain sensitive information.
