Synopsis
========
Multiple vulnerabilities have been found in libarchive, some of which
may allow execution of arbitrary code.

Background
==========
libarchive is a library for manipulating different streaming archive
formats, including certain tar variants, several cpio formats, and both
BSD and GNU ar variants.

Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-arch/libarchive < 3.1.2-r1 >= 3.1.2-r1

Description
===========
Multiple vulnerabilities have been discovered in libarchive. Please
review the CVE identifiers referenced below for details.

Impact
======
A remote attacker could entice a user or automated process to open a
specially crafted archive using an application linked against
libarchive, possibly resulting in 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 libarchive users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=app-arch/libarchive-3.1.2-r1"

Packages which depend on this library may need to be recompiled. Tools
such as revdep-rebuild may assist in identifying some of these
packages.
