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: 8.9
SynopsisThe remote device is missing a vendor-supplied security patch
DescriptionThe remote host is running a version of RancherOS prior to 1.4.0, hence is exposted to a side-channel vulnerabilities:
- Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis.(CVE-2017-5753)
- A statement in the System Programming Guide of the Intel 64 and IA-32 Architectures Software Developer’s Manual (SDM) was mishandled in the development of some or all operating-system kernels, resulting in unexpected behavior for #DB exceptions that are deferred by MOV SS or POP SS, as demonstrated by (for example) privilege escalation in Windows, macOS, some Xen configurations, or FreeBSD, or a Linux kernel crash. (CVE-2018-8897)
SolutionUpgrade to RancherOS v1.4.0 or later
