Ubuntu 4.10 / 5.04 : mozilla, mozilla-firefox vulnerabilities (USN-186-1)

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

Description :

Peter Zelezny discovered that URLs which are passed to Firefox or
Mozilla on the command line are not correctly protected against
interpretation by the shell. If Firefox or Mozilla is configured as
the default handler for URLs (which is the default in Ubuntu), this
could be exploited to execute arbitrary code with user privileges by
tricking the user into clicking on a specially crafted URL (for
example, in an email or chat client). (CAN-2005-2968, MFSA-2005-59)

A buffer overflow was discovered in the XBM image handler. By tricking
an user into opening a specially crafted XBM image, an attacker could
exploit this to execute arbitrary code with the user's privileges.

Mats Palmgren discovered a buffer overflow in the Unicode string
parser. Unicode strings that contained 'zero-width non-joiner'
characters caused a browser crash, which could possibly even exploited
to execute arbitrary code with the user's privileges. (MFSA-2005-58)

Georgi Guninski reported an integer overflow in the JavaScript engine.
This could be exploited to run arbitrary code under some conditions.

This update also fixes some less critical issues which are described
at http://www.mozilla.org/security/announce/mfsa2005-58.html.

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.
