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.

Synopsis
The remote EulerOS host is missing multiple security updates.
Description
According 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 :
- Multiple flaws were discovered in the Serialization and Hotspot components in OpenJDK. An untrusted Java application or applet could use these flaws to completely bypass Java sandbox restrictions.(CVE-2016-0686, CVE-2016-0687)
- It was discovered that the RMI server implementation in the JMX component in OpenJDK did not restrict which classes can be deserialized when deserializing authentication credentials. A remote, unauthenticated attacker able to connect to a JMX port could possibly use this flaw to trigger deserialization flaws.
(CVE-2016-3427)
- It was discovered that the JAXP component in OpenJDK failed to properly handle Unicode surrogate pairs used as part of the XML attribute values. Specially crafted XML input could cause a Java application to use an excessive amount of memory when parsed.(CVE-2016-3425)
- It was discovered that the Security component in OpenJDK failed to check the digest algorithm strength when generating DSA signatures.The use of a digest weaker than the key strength could lead to the generation of signatures that were weaker than expected.(CVE-2016-0695)
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.
Solution
Update the affected java-1.7.0-openjdk packages.
