==========================================================================
Ubuntu Security Notice USN-3366-2
July 31, 2017

openjdk-8 regression
==========================================================================

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

- Ubuntu 17.04
- Ubuntu 16.04 LTS

Summary:

USN 3366-1 introduced a regression in OpenJDK 8.

Software Description:
- openjdk-8: Open Source Java implementation

Details:

USN-3366-1 fixed vulnerabilities in OpenJDK 8. Unfortunately, that
update introduced a regression that caused some valid JAR files to
fail validation. This update fixes the problem.

We apologize for the inconvenience.

Original advisory details:

 It was discovered that the JPEGImageReader class in OpenJDK would
 incorrectly read unused image data. An attacker could use this to
 specially construct a jpeg image file that when opened by a Java
 application would cause a denial of service. (CVE-2017-10053)

 It was discovered that the JAR verifier in OpenJDK did not properly
 handle archives containing files missing digests. An attacker could
 use this to modify the signed contents of a JAR file. (CVE-2017-10067)

 It was discovered that integer overflows existed in the Hotspot
 component of OpenJDK when generating range check loop predicates. An
 attacker could use this to specially construct an untrusted Java
 application or applet that could escape sandbox restrictions
 and cause a denial of service or possibly execute arbitrary
 code. (CVE-2017-10074)

 It was discovered that the JavaScript Scripting component of OpenJDK
 incorrectly allowed access to Java APIs. An attacker could use this
 to specially craft JavaScript code to bypass access restrictions.
 (CVE-2017-10078)

 It was discovered that OpenJDK did not properly process parentheses
 in function signatures. An attacker could use this to specially
 construct an untrusted Java application or applet that could escape
 sandbox restrictions. (CVE-2017-10081)

 It was discovered that the ThreadPoolExecutor class in OpenJDK did not
 properly perform access control checks when cleaning up threads. An
 attacker could use this to specially construct an untrusted Java
 application or applet that could escape sandbox restrictions and
 possibly execute arbitrary code. (CVE-2017-10087)

 It was discovered that the ServiceRegistry implementation
 in OpenJDK did not perform access control checks in certain
 situations. An attacker could use this to specially construct
 an untrusted Java application or applet that escaped sandbox
 restrictions. (CVE-2017-10089)

 It was discovered that the channel groups implementation in
 OpenJDK did not properly perform access control checks in some
 situations. An attacker could use this to specially construct an
 untrusted Java application or applet that could escape sandbox
 restrictions. (CVE-2017-10090)

 It was discovered that the DTM exception handling code in the
 JAXP component of OpenJDK did not properly perform access control
 checks. An attacker could use this to specially construct an untrusted
 Java application or applet that could escape sandbox restrictions.
 (CVE-2017-10096)

 It was discovered that the JAXP component of OpenJDK incorrectly
 granted access to some internal resolvers. An attacker could use this
 to specially construct an untrusted Java application or applet that
 could escape sandbox restrictions. (CVE-2017-10101)

 It was discovered that the Distributed Garbage Collector (DGC) in
 OpenJDK did not properly track references in some situations. A
 remote attacker could possibly use this to execute arbitrary
 code. (CVE-2017-10102)

 It was discovered that the Activation ID implementation in the RMI
 component of OpenJDK did not properly check access control permissions
 in some situations. An attacker could use this to specially construct
 an untrusted Java application or applet that could escape sandbox
 restrictions. (CVE-2017-10107)

 It was discovered that the BasicAttribute class in OpenJDK did not
 properly bound memory allocation when de-serializing objects. An
 attacker could use this to cause a denial of service (memory
 consumption). (CVE-2017-10108)

 It was discovered that the CodeSource class in OpenJDK did not
 properly bound memory allocations when de-serializing object
 instances. An attacker could use this to cause a denial of service
 (memory consumption). (CVE-2017-10109)

 It was discovered that the AWT ImageWatched class in OpenJDK did not
 properly perform access control checks, An attacker could use this
 to specially construct an untrusted Java application or applet that
 could escape sandbox restrictions (CVE-2017-10110)

 Jackson Davis discovered that the LambdaFormEditor class in the
 Libraries component of OpenJDK did not correctly perform bounds checks
 in the permuteArgumentsForm() function. An attacker could use this
 to specially construct an untrusted Java application or applet that
 could escape sandbox restrictions and possibly execute arbitrary
 code. (CVE-2017-10111)

 It was discovered that a timing side-channel vulnerability existed
 in the DSA implementation in OpenJDK. An attacker could use this to
 expose sensitive information. (CVE-2017-10115)

 It was discovered that the LDAP implementation in OpenJDK incorrectly
 followed references to non-LDAP URLs. An attacker could use this to
 specially craft an LDAP referral URL that exposes sensitive information
 or bypass access restrictions. (CVE-2017-10116)

 It was discovered that a timing side-channel vulnerability existed
 in the ECDSA implementation in OpenJDK. An attacker could use this
 to expose sensitive information. (CVE-2017-10118)

 Ilya Maykov discovered that a timing side-channel vulnerability
 existed in the PKCS#8 implementation in OpenJDK. An attacker could
 use this to expose sensitive information. (CVE-2017-10135)

 It was discovered that the Elliptic Curve (EC) implementation
 in OpenJDK did not properly compute certain elliptic curve
 points. An attacker could use this to expose sensitive
 information. (CVE-2017-10176)

 It was discovered that OpenJDK did not properly restrict weak key
 sizes in some situations. An attacker could use this to specially
 construct an untrusted Java application or applet that could escape
 sandbox restrictions. (CVE-2017-10193)

 It was discovered that OpenJDK did not properly enforce disabled
 algorithm restrictions on X.509 certificate chains. An attacker
 could use this to expose sensitive information or escape sandbox
 restrictions. (CVE-2017-10198)

 It was discovered that OpenJDK did not properly perform access control
 checks when handling Web Service Definition Language (WSDL) XML
 documents. An attacker could use this to expose sensitive information.
 (CVE-2017-10243)

Update instructions:

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

Ubuntu 17.04:
  openjdk-8-jre                   8u131-b11-2ubuntu1.17.04.3
  openjdk-8-jre-headless          8u131-b11-2ubuntu1.17.04.3
  openjdk-8-jre-zero              8u131-b11-2ubuntu1.17.04.3

Ubuntu 16.04 LTS:
  openjdk-8-jre                   8u131-b11-2ubuntu1.16.04.3
  openjdk-8-jre-headless          8u131-b11-2ubuntu1.16.04.3
  openjdk-8-jre-jamvm             8u131-b11-2ubuntu1.16.04.3
  openjdk-8-jre-zero              8u131-b11-2ubuntu1.16.04.3

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.
