CVE-2017-10198 Amazon Linux Security Advisory for java-1.7.0-openjdk: ALAS-2017-936

It was discovered that the Security component of OpenJDK could fail to properly enforce restrictions defined for processing of X.509 certificate chains. A remote attacker could possibly use this flaw to make Java accept certificate using one of the disabled algorithms. (CVE-2017-10198 )

Vulnerability in the Java SE, Java SE Embedded component of Oracle Java SE (subcomponent: Hotspot). Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Java SE, Java SE Embedded, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of Java SE, Java SE Embedded. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability does not apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed by an administrator). (CVE-2017-10346 )

Vulnerability in the Java SE, JRockit component of Oracle Java SE (subcomponent: Serialization). Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, JRockit. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Java SE, JRockit. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability does not apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed by an administrator). (CVE-2017-10347 )
