CVE-2013-3949
Last modified
CVE-2013-3949 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.49% chance of exploitation in the next 30 days.
