USN-2549-1

It was discovered that the libarchive bsdcpio utility extracted absolute paths by default without using the --insecure flag, contrary to expectations. If a user or automated system were tricked into extracting cpio archives containing absolute paths, a remote attacker may be able to write to arbitrary files. (CVE-2015-2304)

Fabian Yamaguchi discovered that libarchive incorrectly handled certain type conversions. A remote attacker could possibly use this issue to cause libarchive to crash, resulting in a denial of service. This issue only affected Ubuntu 12.04 LTS. (CVE-2013-0211)
