Mandriva Linux Security Advisory - Buffer overflow in the safer_name_suffix function in GNU cpio has unspecified attack vectors and impact, resulting in a crashing stack. This problem is originally found in tar, but affects cpio too, due to similar code fragments. Directory traversal vulnerability in cpio 2.6 and earlier allows remote attackers to write to arbitrary directories via a .. (dot dot) in a cpio file. This is an old issue, affecting only Mandriva Corporate Server 4 and Mandriva Linux 2007.

c665205959ec8f3619720b2de74392a8140fdb744d012e6f45e8a52f82aa1760Ubuntu Security Notice USN-189-1 - Imran Ghory found a race condition in the handling of output files. While a file was unpacked with cpio, a local attacker with write permissions to the target directory could exploit this to change the permissions of arbitrary files of the cpio user. (CVE-2005-1111) Imran Ghory also discovered a path traversal vulnerability. Even when the --no-absolute-filenames option was specified, cpio did not filter out ".." path components. By tricking an user into unpacking a malicious cpio archive, this could be exploited to install files in arbitrary paths with the privileges of the user calling cpio. (CVE-2005-1229)
