Ubuntu 4.10 / 5.04 : ruby1.8 vulnerability (USN-195-1)

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


Synopsis :

The remote Ubuntu host is missing one or more security-related
patches.

Description :

The object oriented scripting language Ruby supports safely executing
untrusted code with two mechanisms: safe level and taint flag on
objects. Dr. Yutaka Oiwa discovered a vulnerability that allows Ruby
methods to bypass these mechanisms. In systems which use this feature,
this could be exploited to execute Ruby code beyond the restrictions
specified in each safe level.

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 packages.

Risk factor :

High / CVSS Base Score : 7.5
(CVSS2#AV:N/AC:L/Au:N/C:P/I:P/A:P)
