Package        : cpio
CVE ID         : CVE-2014-9112
Debian Bug     : 772793

Michal Zalewski discovered an out of bounds write issue in cpio, a tool
for creating and extracting cpio archive files.  In the process of
fixing that issue, the cpio developers found and fixed additional
range checking and null pointer dereference issues.

For the stable distribution (wheezy), this problem has been fixed in
version 2.11+dfsg-0.1+deb7u1.

For the upcoming stable distribution (jessie), this problem will be
fixed soon.

For the unstable distribution (sid), this problem has been fixed in
version 2.11+dfsg-4.

We recommend that you upgrade your cpio packages.
