Amazon Linux AMI : java-1.7.0-openjdk (ALAS-2017-835)

high Nessus Plugin ID 100636

Language:

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

An untrusted library search path flaw was found in the JCE component of

OpenJDK. A local attacker could possibly use this flaw to cause a Java

application using JCE to load an attacker-controlled library and hence escalate

their privileges. (CVE-2017-3511)

It was found that the JAXP component of OpenJDK failed to correctly enforce

parse tree size limits when parsing XML document. An attacker able to make a

Java application parse a specially crafted XML document could use this flaw to

make it consume an excessive amount of CPU and memory. (CVE-2017-3526)

It was discovered that the HTTP client implementation in the Networking

component of OpenJDK could cache and re-use an NTLM authenticated connection in

a different security context. A remote attacker could possibly use this flaw to

make a Java application perform HTTP requests authenticated with credentials of

a different user. (CVE-2017-3509)

It was discovered that the Security component of OpenJDK did not allow users

to restrict the set of algorithms allowed for Jar integrity verification. This

flaw could allow an attacker to modify content of the Jar file that used weak

signing key or hash algorithm. (CVE-2017-3539)

Newline injection flaws were discovered in FTP and SMTP client implementations

in the Networking component in OpenJDK. A remote attacker could possibly use

these flaws to manipulate FTP or SMTP connections established by a Java

application. (CVE-2017-3533 , CVE-2017-3544)

Note: This update adds support for the 'jdk.ntlm.cache' system property which,

when set to false, prevents caching of NTLM connections and authentications and

hence prevents this issue. However, caching remains enabled by default.

Note: This updates extends the fix for CVE-2016-5542 released as part of the

RHSA-2016-2658 erratum to no longer allow the MD5 hash algorithm during the Jar

integrity verification by adding it to the jdk.jar.disabledAlgorithms security

property.

Solution

Run 'yum update java-1.7.0-openjdk' to update your system.
