Ubuntu 4.10 / 5.04 : cpio vulnerabilities (USN-189-1)

Ubuntu Security Notice (C) 2005-2016 Canonical, Inc. / NASL script (C) 2006-2016 Tenable Network Security, Inc.

Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

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).

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.

Solution :

Update the affected cpio package.

Risk factor :

Medium / CVSS Base Score : 4.6
CVSS Temporal Score : 4.0
Public Exploit Available : true
