Description

The specific version of PHP that the system is running is reportedly affected by the following vulnerabilities:

- Apple Mac OS X contains an overflow condition in the NVIDIA Graphics Driver (GeForce.kext). This may allow a local attacker to cause a stack-based buffer overflow and potentially execute arbitrary code with kernel privileges. (CVE-2016-1861)

- Apple Mac OS X contains an unspecified flaw in the Intel Graphics Driver. This may allow a local attacker to gain knowledge of kernel memory layout and in turn bypass security mechanisms like Kernel Address Space Layout Randomization (KASLR). (CVE-2016-1862)
