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: 8.1
SynopsisThe remote EulerOS host is missing multiple security updates.
DescriptionAccording to the versions of the java-1.7.0-openjdk packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
- OpenJDK: incorrect handling of Reference clones can lead to sandbox bypass.(CVE-2018-2814)
- OpenJDK: unrestricted deserialization of data from JCEKS key stores.(CVE-2018-2794)
- OpenJDK: insufficient consistency checks in deserialization of multiple classes.(CVE-2018-2795)
- OpenJDK: unbounded memory allocation during deserialization in PriorityBlockingQueue.(CVE-2018-2796)
- OpenJDK: unbounded memory allocation during deserialization in TabularDataSupport. (CVE-2018-2797)
- OpenJDK: unbounded memory allocation during deserialization in Container.(CVE-2018-2798)
- OpenJDK: unbounded memory allocation during deserialization in NamedNodeMapImpl.(CVE-2018-2799)
- OpenJDK: RMI HTTP transport enabled by default.(CVE-2018-2800)
- OpenJDK: unbounded memory allocation during deserialization in StubIORImpl.(CVE-2018-2815)
- OpenJDK: incorrect merging of sections in the JAR manifest.(CVE-2018-2790)
- An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of Load i1/4+ Store instructions (a commonly used performance optimization). It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory read from address to which a recent memory write has occurred may see an older value and subsequently cause an update into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to read privileged memory by conducting targeted cache side-channel attacks.(CVE-2018-3639)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
