Severity:	normal
Title:	GNU cpio: Multiple vulnerabilities
Date:	02/15/2015
Bugs:	#530512, #536010
ID:	201502-11

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	Architecture(s)
app-arch/cpio	< 2.11-r3	>= 2.11-r3	All supported architectures

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"
