Description:
Apple Mac OS X and Mac OS X Server could allow a local attacker to execute arbitrary commands on the system with elevated privileges, caused by a format string vulnerability in the launchd logging function. A local authenticated user could exploit this vulnerability by passing specially-crafted format specifiers to the CF_syslog() function using a malicious plist file, allowing the attacker to execute arbitrary commands on the system with elevated privileges.
