(Red Hat Issues Fix for Oracle Java SE) Intel/AMD/ARM CPU Cache Race Conditions Let Local Users Read Arbitrary Register and Memory Contents
SecurityTracker Alert ID:  1040954
SecurityTracker URL:  http://securitytracker.com/id/1040954
CVE Reference:   CVE-2018-3639   (Links to External Site)
Date:  May 22 2018
Impact:   Disclosure of system information
Fix Available:  Yes  Vendor Confirmed:  Yes  

Description:   Two vulnerabilities were reported in Intel, AMD, and ARM CPUs. A local user can obtain potentially sensitive information from system memory. Oracle Java SE is affected.

A local user can exploit race conditions in CPU cache processing to obtain potentially sensitive information on the target system. This can be exploited to read arbitrary system register and memory contents on the target system.

A local user can conduct a side-channel attack to exploit a flaw in the speculative loading of system registers to read privileged system registers [CVE-2018-3640].

The CVE-2018-3640 vulnerability is referred to as "Spectre variant 3A".

A local user can conduct a side-channel attack to exploit a flaw in the speculative execution of Load and Store instructions to read privileged memory [CVE-2018-3639].

The CVE-2018-3639 vulnerability is referred to as "Spectre variant 4".

The original advisory is available at:

https://bugs.chromium.org/p/project-zero/issues/detail?id=1528

Zdenek Sojka, Rudolf Marek, and Alex Zuepke from SYSGO AG, Jann Horn (Google Project Zero), and Ken Johnson (Microsoft Security Response Center) reported these vulnerabilities.

Impact:   A local user can view system register or memory contents on the target CPU device.
Solution:   Red Hat has issued a fix for CVE-2018-3639 for Oracle Java SE for java-1.7.0-openjdk.

CVE Names:         CVE-2018-3639 
=====================================================================

1. Summary:

An update for java-1.7.0-openjdk is now available for Red Hat Enterprise
Linux 6.

3. Description:

The java-1.7.0-openjdk packages provide the OpenJDK 7 Java Runtime
Environment and the OpenJDK 7 Java Software Development Kit.

Security Fix(es):

* An industry-wide issue was found in the way many modern microprocessor
designs have implemented speculative execution of Load & Store instructions
(a commonly used performance optimization). It relies on the presence of a
precisely-defined instruction sequence in the privileged code as well as
the fact that memory read from address to which a recent memory write has
occurred may see an older value and subsequently cause an update into the
microprocessor's data cache even for speculatively executed instructions
that never actually commit (retire). As a result, an unprivileged attacker
could use this flaw to read privileged memory by conducting targeted cache
side-channel attacks. (CVE-2018-3639)

Note: This is the OpenJDK side of the CVE-2018-3639 mitigation.

Red Hat would like to thank Ken Johnson (Microsoft Security Response
Center) and Jann Horn (Google Project Zero) for reporting this issue.

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258
