Severity:	normal
Title:	XStream: Remote execution of arbitrary code
Date:	12/13/2016
Bugs:	#497652
ID:	201612-35

Synopsis

A vulnerability in XStream may allow remote attackers to execute arbitrary code.

Background

XStream is a simple library to serialize objects to XML and back again.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
dev-java/xstream	< 1.4.8-r1	>= 1.4.8-r1	All supported architectures

Description

It was found that XStream would deserialize arbitrary user-supplied XML content, thus representing objects of any type.

Impact

A remote attacker could pass a specially crafted XML document to XStream, possibly resulting in the execution of arbitrary code with the privileges of the process or a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All XStream users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-java/xstream-1.4.8-r1"
