Synopsis
========
Two vulnerabilities have been found in GNU cpio, the worst of which
could result in execution of arbitrary code.

Background
==========
GNU cpio copies files into or out of a cpio or tar archive.

Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-arch/cpio < 2.11-r3 >= 2.11-r3

Description
===========
Two vulnerabilities have been discovered in GNU cpio:

* The list_file function in GNU cpio contains a heap-based buffer
overflow vulnerability (CVE-2014-9112)
* A directory traversal vulnerability has been found in GNU cpio
(CVE-2015-1197)

Impact
======
A remote attacker may be able to entice a user to open a specially
crafted archive using GNU cpio, possibly resulting in execution of
arbitrary code, a Denial of Service condition, or overwriting arbitrary
files.

Workaround
==========
There is no known workaround at this time.

Resolution
==========
All GNU cpio users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=app-arch/cpio-2.11-r3"
