Ubuntu Security Notice 3824-1 - 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. 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. Various other issues were also addressed.

openjdk-7 vulnerabilities
==========================================================================

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

- Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in OpenJDK 7.

Software Description:
- openjdk-7: 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 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)

Update instructions:

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

Ubuntu 14.04 LTS:
icedtea-7-jre-jamvm 7u181-2.6.14-0ubuntu0.3
openjdk-7-jdk 7u181-2.6.14-0ubuntu0.3
openjdk-7-jre 7u181-2.6.14-0ubuntu0.3
openjdk-7-jre-headless 7u181-2.6.14-0ubuntu0.3
openjdk-7-jre-lib 7u181-2.6.14-0ubuntu0.3

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.
