Description

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).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
