Ubuntu Security Notice USN-3275-3

openjdk-7 regression
==========================================================================

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

- Ubuntu 14.04 LTS

Summary:

USN-3275-2 introduced a regression in OpenJDK 7.

Software Description:
- openjdk-7: Open Source Java implementation

Details:

USN-3275-2 fixed vulnerabilities in OpenJDK 7. Unfortunately, the
update introduced a regression when handling TLS handshakes. This
update fixes the problem.

We apologize for the inconvenience.

Original advisory details:

 It was discovered that OpenJDK improperly re-used cached NTLM
 connections in some situations. A remote attacker could possibly
 use this to cause a Java application to perform actions with the
 credentials of a different user. (CVE-2017-3509)

 It was discovered that an untrusted library search path flaw existed
 in the Java Cryptography Extension (JCE) component of OpenJDK. A
 local attacker could possibly use this to gain the privileges of a
 Java application. (CVE-2017-3511)

 It was discovered that the Java API for XML Processing (JAXP) component
 in OpenJDK did not properly enforce size limits when parsing XML
 documents. An attacker could use this to cause a denial of service
 (processor and memory consumption). (CVE-2017-3526)

 It was discovered that the FTP client implementation in OpenJDK did
 not properly sanitize user inputs. If a user was tricked into opening
 a specially crafted FTP URL, a remote attacker could use this to
 manipulate the FTP connection. (CVE-2017-3533)

 It was discovered that OpenJDK allowed MD5 to be used as an algorithm
 for JAR integrity verification. An attacker could possibly use this
 to modify the contents of a JAR file without detection. (CVE-2017-3539)

 It was discovered that the SMTP client implementation in OpenJDK
 did not properly sanitize sender and recipient addresses. A remote
 attacker could use this to specially craft email addresses and gain
 control of a Java application's SMTP connections. (CVE-2017-3544)

Update instructions:

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

Ubuntu 14.04 LTS:
  icedtea-7-jre-jamvm             7u131-2.6.9-0ubuntu0.14.04.2
  openjdk-7-jre                   7u131-2.6.9-0ubuntu0.14.04.2
  openjdk-7-jre-headless          7u131-2.6.9-0ubuntu0.14.04.2
  openjdk-7-jre-lib               7u131-2.6.9-0ubuntu0.14.04.2
  openjdk-7-jre-zero              7u131-2.6.9-0ubuntu0.14.04.2

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.
