USN-3824-1: OpenJDK 7 vulnerabilities
16 November 2018
openjdk-7 vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
o Ubuntu 14.04 LTS
Summary
Several security issues were fixed in OpenJDK 7.
Software Description
o 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)
