Ubuntu Security Notice (C) 2005-2016 Canonical, Inc. / NASL script (C) 2006-2016 Tenable Network Security, Inc.
The remote Ubuntu host is missing one or more security-related
It was discovered that a malicious website could inject arbitrary
scripts into a target site by loading it into a frame and navigating
could be used to steal cookies or other confidential data from the
target site. If the target site is allowed to raise the install
confirmation dialog in Firefox then this flaw even allowed the
malicious site to execute arbitrary code with the privileges of the
Firefox user. By default only the Mozilla Update site is allowed to
attempt software installation
however, users can permit this for
additional sites. (MFSA 2005-42)
Michael Krax, Georgi Guninski, and L. David Baron found that the
security checks that prevent script injection could be bypassed by
'view-source:' or 'jar:'. (CAN-2005-1531)
A variant of the attack described in CAN-2005-1160 (see USN-124-1) was
and Script objects are run with the privileges of the context that
created them, not the potentially elevated privilege of the context
calling them. (CAN-2005-1532)
Note: These flaws also apply to Ubuntu 5.04's Mozilla, and to the
Ubuntu 4.10 versions of Firefox and Mozilla. These will be fixed soon.
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.
Update the affected packages.
