Ubuntu 4.10 : cpio vulnerability (USN-75-1)

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 :

Recently it was discovered that cpio created world-writeable files
when used in -o/--create mode with giving an output file (with -O).
This allowed any user to modify the created cpio archives. Now cpio
respects the current umask setting of the user.

Note: This vulnerability has already been fixed in a very old version
of cpio, but the fix was never ported to the current version.
Therefore the CAN number was assigned to the year 1999.

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 :

Low / CVSS Base Score : 2.1
(CVSS2#AV:L/AC:L/Au:N/C:P/I:N/A:N)
