GNU cpio: Multiple vulnerabilities

GNU cpio: Multiple vulnerabilities Two vulnerabilities have been found in GNU cpio, the worst of which could result in execution of arbitrary code. cpio 2015-02-15 2015-02-15 530512 536010 remote 2.11-r3 2.11-r3

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

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)

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.

There is no known workaround at this time.

All GNU cpio users should upgrade to the latest version:


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