Ubuntu Security Notice (C) 2005-2013 Canonical, Inc. / NASL script (C) 2006-2013 Tenable Network Security, Inc.
The remote Ubuntu host is missing a security-related patch.
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. (CAN-2005-1111)
Imran Ghory 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. (CAN-2005-1229).
Update the affected cpio package.
