Scientific Linux Security Update : java-1.7.0-openjdk on SL6.x, SL7.x i386/x86_64

This script is Copyright (C) 2017 Tenable Network Security, Inc.

Synopsis :

The remote Scientific Linux host is missing one or more security

Description :

Security Fix(es) :

- 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)

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.

- 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)

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

- 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)
