"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).
