Techradar posted a story that a researcher uncovered a security exploit in Apple's latest OS X operating system that allows your Mac to grant privilege escalation to attackers.

In turn, attackers can gain control and hijack your Mac. The exploit affects systems running OS X Yosemite. Security researcher Stephan Esser discovered that the vulnerability was not present in the early OS X 10.11 El Capitan betas, but remains unpatched in OS X10.10.4 and the beta of OS X 10.10.5, so it remains unclear if Apple is aware of this vulnerability.The vulnerability is the result of the way that errors are logged in OS X.Changes to OS X that enables the vulnerabilityApple made changes to the dynamic linker dyld with the release of OS X Yosemite, allowing the DYLD_PRINT_TO_FILE to write errors to an arbitrary file.Under normal circumstances, the dynamic linker would reject environmental variables passed to it for restricted files, but Apple didn't implement any safeguards in Yosemite.
