CVE Author: NIST National Vulnerability Database

CVSS Base Vector:

Detection Type:
Linux Distribution Package

Check the version of java

Detection Method:
Checks if a vulnerable version is present on the target host.

Technical Details:
The java-1.7.0-openjdk Linux Distribution Packages provide the OpenJDK 7 Java Runtime Environment and the OpenJDK 7 Java Software Development Kit. Security Fix(es): * It was discovered that the RMI Windows Registry and DCG implementations in the RMI component of OpenJDK performed deserialization of untrusted inputs. A remote attacker could possibly use this flaw to execute arbitrary code with the privileges of RMI Windows Registry or a Java RMI application. (CVE-2017-3241) This issue was addressed by introducing whitelists of classes that can be deserialized by RMI Windows Registry or DCG. These whitelists can be customized using the newly introduced sun.rmi.Windows Registry.Windows RegistryFilter and sun.rmi.transport.dgcFilter security properties. * Multiple flaws were discovered in the Libraries and Hotspot components in OpenJDK. An untrusted Java application or applet could use these flaws to completely bypass Java sandbox restrictions. (CVE-2017-3272, CVE-2017-3289) * A covert timing channel flaw was found in the DSA implementation in the Libraries component of OpenJDK. A remote attacker could possibly use this flaw to extract certain information about the used key via a timing side channel. (CVE-2016-5548) * It was discovered that the Libraries component of OpenJDK accepted ECSDA signatures using non-canonical DER encoding. This could cause a Java application to accept signature in an incorrect format not accepted by other cryptographic tools. (CVE-2016-5546) * It was discovered that the 2D component of OpenJDK performed parsing of iTXt and zTXt PNG image chunks even when configured to ignore metadata. An attacker able to make a Java application parse a specially crafted PNG image could cause the application to consume an excessive amount of memory. (CVE-2017-3253) * It was discovered that the Libraries component of OpenJDK did not validate the length of the object identifier read from the DER input before allocating memory to store the OID. An attacker able to make a Java application decode a specially crafted DER input could cause the application to consume an excessive amount of memory. (CVE-2016-5547) * It was discovered that the JAAS component of OpenJDK did not use the correct way to extract user DN from the result of the user search LDAP query. A specially crafted user LDAP entry could cause the application to use an incorrect DN. (CVE-2017-3252) * It was discovered that the Networking component of OpenJDK failed to properly parse user info from the URL. A remote attacker could cause a Java application to incorrectly parse an attacker supplied URL and interpret it differently from other applications processing the same URL. (CVE-2016- ...

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
