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.
