Ubuntu Security Notice USN-3691-1
June 21, 2018

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 correctly
perform merging of multiple sections for the same file listed in JAR
archive file manifests. An attacker could possibly use this to modify
attributes in a manifest without invalidating the signature.
(CVE-2018-2790)

Francesco Palmarini, Marco Squarcina, Mauro Tempesta, and Riccardo Focardi
discovered that the Security component of OpenJDK did not restrict which
classes could be used when deserializing keys from the JCEKS key stores. An
attacker could use this to specially craft a JCEKS key store to execute
arbitrary code. (CVE-2018-2794)

It was discovered that the Security component of OpenJDK in some situations
did not properly limit the amount of memory allocated when performing
deserialization. An attacker could use this to cause a denial of service
(memory exhaustion). (CVE-2018-2795)

It was discovered that the Concurrency component of OpenJDK in some
situations did not properly limit the amount of memory allocated when
performing deserialization. An attacker could use this to cause a denial of
service (memory exhaustion). (CVE-2018-2796)

It was discovered that the JMX component of OpenJDK in some situations did
not properly limit the amount of memory allocated when performing
deserialization. An attacker could use this to cause a denial of service
(memory exhaustion). (CVE-2018-2797)

It was discovered that the AWT component of OpenJDK in some situations did
not properly limit the amount of memory allocated when performing
deserialization. An attacker could use this to cause a denial of service
(memory exhaustion). (CVE-2018-2798)

It was discovered that the JAXP component of OpenJDK in some situations did
not properly limit the amount of memory allocated when performing
deserialization. An attacker could use this to cause a denial of service
(memory exhaustion). (CVE-2018-2799)

Moritz Bechler discovered that the RMI component of OpenJDK enabled HTTP
transport for RMI servers by default. A remote attacker could use this to
gain access to restricted services. (CVE-2018-2800)

It was discovered that a vulnerability existed in the Hotspot component of
OpenJDK affecting confidentiality, data integrity, and availability. An
attacker could use this to specially craft an Java application that caused
a denial of service or bypassed sandbox restrictions. (CVE-2018-2814)

Apostolos Giannakidis discovered that the Serialization component of
OpenJDK did not properly bound memory allocations in some situations. An
attacker could use this to cause a denial of service (memory exhaustion).
(CVE-2018-2815)

Update instructions:

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

Ubuntu 14.04 LTS:
icedtea-7-jre-jamvm 7u181-2.6.14-0ubuntu0.1
openjdk-7-jre 7u181-2.6.14-0ubuntu0.1
openjdk-7-jre-headless 7u181-2.6.14-0ubuntu0.1
openjdk-7-jre-lib 7u181-2.6.14-0ubuntu0.1
openjdk-7-jre-zero 7u181-2.6.14-0ubuntu0.1

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.
