ID de Prueba:1.3.6.1.4.1.25623.1.0.55417
Categoría:Ubuntu Local Security Checks
Título:Ubuntu USN-186-1 (mozilla-firefox)
Resumen:Ubuntu USN-186-1 (mozilla-firefox)
Descripción:
The remote host is missing an update to mozilla-firefox
announced via advisory USN-186-1.

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)
Ubuntu 5.04 (Hoary Hedgehog)

The following packages are affected:

mozilla-browser
mozilla-calendar
mozilla-mailnews
mozilla-firefox

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). (CVE-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.
(MFSA-2005-58)

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.
(MFSA-2005-58)

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

Solution:
On Ubuntu 4.10, the problem can be corrected by upgrading the affected
package to version 2:1.7.12-0ubuntu04.10 (mozilla-browser,
mozilla-calendar, mozilla-mailnews).

On Ubuntu 5.04, the problem can be corrected by upgrading the affected
package to version 2:1.7.12-0ubuntu05.04 (mozilla-browser,
mozilla-calendar, mozilla-mailnews) and 1.0.7-0ubuntu0.1
(mozilla-firefox).

After a standard system upgrade you need to restart all Firefox and
Mozilla browsers to effect the necessary changes.

Note: The Ubuntu 4.10 version of Firefox is also affected by this. An
update will follow shortly.
