New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 6.7
SynopsisThe remote host is affected by multiple vulnerabilities.
DescriptionThe remote Mac OS X host is running EFI firmware that is affected by multiple vulnerabilities :
- An insufficient locking issue exists, when resuming from sleep states, which allows a local attacker to write to the EFI flash memory by using an crafted application with root privileges. (CVE-2015-3692)
- A flaw exists due to lax restrictions on memory refresh rates, which allows a specially crafted process to corrupt the memory of some DDR3 SDRAM devices by inducing bit flips in page table entries (PTEs), also known as a 'row-hammer attack'. An attacker can exploit this to gain elevated privileges by manipulating the PTEs. (CVE-2015-3693)
