Summary
=======

The package jre8-openjdk-headless before version 8.u45-1 is vulnerable
to multiple issues including but not limited to arbitrary code
execution, directory traversal, sandbox restriction bypass and denial of
service.

Resolution
==========

Upgrade to 8.u45-1.

# pacman -Syu "jre8-openjdk-headless>=8.u45-1"

The problems have been fixed upstream in version 8.u45-1.

Workaround
==========

None.

Description
===========

- CVE-2005-1080 CVE-2015-0480 (directory traversal)

A directory traversal flaw was found in the way the jar tool extracted
JAR archive files. A specially crafted JAR archive could cause jar to
overwrite arbitrary files writable by the user running jar when the
archive was extracted.

- CVE-2015-0460 (arbitrary code execution)

A flaw was found in the way the Hotspot component in OpenJDK handled
phantom references. An untrusted Java application or applet could use
this flaw to corrupt the Java Virtual Machine memory and, possibly,
execute arbitrary code, bypassing Java sandbox restrictions.

- CVE-2015-0469 (arbitrary code execution)

An off-by-one flaw, leading to a buffer overflow, was found in the font
parsing code in the 2D component in OpenJDK. A specially crafted font
file could possibly cause the Java Virtual Machine to execute arbitrary
code, allowing an untrusted Java application or applet to bypass Java
sandbox restrictions.

- CVE-2015-0470 (sandbox restriction bypass)

A flaw was discovered in the Hotspot component in OpenJDK. An untrusted
Java application or applet could use these flaws to bypass certain Java
sandbox restrictions.

- CVE-2015-0477 (sandbox restriction bypass)

A flaw was discovered in the Beans component in OpenJDK. An untrusted
Java application or applet could use these flaws to bypass certain Java
sandbox restrictions.

- CVE-2015-0478 (weak implementation)

It was found that the RSA implementation in the JCE component in OpenJDK
did not follow recommended practices for implementing RSA signatures.

- CVE-2015-0488 (denial of service)

A flaw was found in the way the JSSE component in OpenJDK parsed X.509
certificate options. A specially crafted certificate could cause JSSE to
raise an exception, possibly causing an application using JSSE to exit
unexpectedly.

Impact
======

A remote attacker is able to execute arbitrary code, perform directory
traversal, bypass certain sandbox restrictions or perform a denial of
service attack via various vectors.
