Gentoo Linux Security Advisory

Title: GNU cpio: Multiple vulnerabilities (GLSA 201502-11)
Severity: normal
Exploitable: remote
Date: February 15, 2015
Bug(s): #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: app-arch/cpio
Vulnerable: < 2.11-r3
Unaffected: >= 2.11-r3
Architectures: 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:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=app-arch/cpio-2.11-r3"
