cpio vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.10
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS
Summary:
The GNU cpio program could be made to crash or run programs if it
opened a specially crafted file or received specially crafted input.
Software Description:
- cpio: a program to manage archives of files
Details:
Michal Zalewski discovered an out of bounds write issue in the
process_copy_in function of GNU cpio. An attacker could specially
craft a cpio archive that could create a denial of service or possibly
execute arbitrary code. (CVE-2014-9112)
Jakob Lell discovered a heap-based buffer overflow in the rmt_read__
function of GNU cpio's rmt client functionality. An attacker
controlling a remote rmt server could use this to cause a denial of
service or possibly execute arbitrary code. This issue only affected
Ubuntu 10.04 LTS. (CVE-2010-0624)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 14.10:
cpio 2.11+dfsg-2ubuntu1.1
Ubuntu 14.04 LTS:
cpio 2.11+dfsg-1ubuntu1.1
Ubuntu 12.04 LTS:
cpio 2.11-7ubuntu3.1
Ubuntu 10.04 LTS:
