Ubuntu Security Notice USN-3804-1
October 30, 2018

openjdk-8, openjdk-lts vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- - Ubuntu 18.10
- - Ubuntu 18.04 LTS
- - Ubuntu 16.04 LTS

Summary:

Several security issues were fixed in OpenJDK.

Software Description:
- - openjdk-lts: Open Source Java implementation
- - openjdk-8: Open Source Java implementation

Details:

It was discovered that the Security component of OpenJDK did not properly
ensure that manifest elements were signed before use. An attacker could
possibly use this to specially construct an untrusted Java application or
applet that could escape sandbox restrictions. (CVE-2018-3136)

Artem Smotrakov discovered that the HTTP client redirection handler
implementation in OpenJDK did not clear potentially sensitive information
in HTTP headers when following redirections to different hosts. An attacker
could use this to expose sensitive information. (CVE-2018-3139)

It was discovered that the Java Naming and Directory Interface (JNDI)
implementation in OpenJDK did not properly enforce restrictions specified
by system properties in some situations. An attacker could potentially use
this to execute arbitrary code. (CVE-2018-3149)

It was discovered that the Utility component of OpenJDK did not properly
ensure all attributes in a JAR were signed before use. An attacker could
use this to specially construct an untrusted Java application or applet
that could escape sandbox restrictions. This issue only affected Ubuntu
18.04 LTS and Ubuntu 18.10. (CVE-2018-3150)

It was discovered that the Hotspot component of OpenJDK did not properly
perform access checks in certain cases when performing field link
resolution. An attacker could use this to specially construct an untrusted
Java application or applet that could escape sandbox restrictions.
(CVE-2018-3169)

Felix Dorre discovered that the Java Secure Socket Extension (JSSE)
implementation in OpenJDK did not ensure that the same endpoint
identification algorithm was used during TLS session resumption as during
initial session setup. An attacker could use this to expose sensitive
information. (CVE-2018-3180)

Krzysztof Szafranski discovered that the Scripting component did not
properly restrict access to the scripting engine in some situations. An
attacker could use this to specially construct an untrusted Java
application or applet that could escape sandbox restrictions.
(CVE-2018-3183)

Tobias Ospelt discovered that the Resource Interchange File Format (RIFF)
reader implementation in OpenJDK contained an infinite loop. An attacker
could use this to cause a denial of service. This issue only affected
Ubuntu 16.04 LTS. (CVE-2018-3214)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 18.10:
  openjdk-11-jdk                  11.0.1+13-2ubuntu1
  openjdk-11-jre                  11.0.1+13-2ubuntu1
  openjdk-11-jre-headless         11.0.1+13-2ubuntu1

Ubuntu 18.04 LTS:
  openjdk-11-jdk                  10.0.2+13-1ubuntu0.18.04.3
  openjdk-11-jre                  10.0.2+13-1ubuntu0.18.04.3
  openjdk-11-jre-headless         10.0.2+13-1ubuntu0.18.04.3

Ubuntu 16.04 LTS:
  openjdk-8-jdk                   8u181-b13-1ubuntu0.16.04.1
  openjdk-8-jre                   8u181-b13-1ubuntu0.16.04.1
  openjdk-8-jre-headless          8u181-b13-1ubuntu0.16.04.1
  openjdk-8-jre-jamvm             8u181-b13-1ubuntu0.16.04.1

This update uses a new upstream release, which includes additional
bug fixes. After a standard system update you need to restart any
Java applications or applets to make all the necessary changes.

Ubuntu Security Notice USN-3830-1

openjdk-8, openjdk-lts regression
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- - Ubuntu 18.04 LTS
- - Ubuntu 16.04 LTS

Summary:

USN-3804-1 introduced a regression in OpenJDK.

Software Description:
- - openjdk-lts: Open Source Java implementation
- - openjdk-8: Open Source Java implementation

Details:

USN-3804-1 fixed vulnerabilities in OpenJDK. Unfortunately, that update
introduced a regression when validating JAR files that prevented Java
applications from finding classes in some situations. This update
fixes the problem.

We apologize for the inconvenience.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 18.04 LTS:
  openjdk-11-jdk                  10.0.2+13-1ubuntu0.18.04.4
  openjdk-11-jre                  10.0.2+13-1ubuntu0.18.04.4
  openjdk-11-jre-headless         10.0.2+13-1ubuntu0.18.04.4

Ubuntu 16.04 LTS:
  openjdk-8-jdk                   8u191-b12-0ubuntu0.16.04.1
  openjdk-8-jre                   8u191-b12-0ubuntu0.16.04.1
  openjdk-8-jre-headless          8u191-b12-0ubuntu0.16.04.1
  openjdk-8-jre-jamvm             8u191-b12-0ubuntu0.16.04.1
