• Ubuntu 12.04
• Ubuntu 10.04

Packages

• 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)
