Ubuntu 7.10 : firefox vulnerabilities (USN-690-2)

Ubuntu Security Notice (C) 2008-2016 Canonical, Inc. / NASL script (C) 2009-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

Several flaws were discovered in the browser engine. These problems
could allow an attacker to crash the browser and possibly execute
arbitrary code with user privileges. (CVE-2008-5500)

Boris Zbarsky discovered that the same-origin check in Firefox could
be bypassed by utilizing XBL-bindings. An attacker could exploit this
to read data from other domains. (CVE-2008-5503)

Several problems were discovered in the JavaScript engine. An attacker
could exploit feed preview vulnerabilities to execute scripts from
page content with chrome privileges. (CVE-2008-5504)

Marius Schilder discovered that Firefox did not properly handle
redirects to an outside domain when an XMLHttpRequest was made to a
same-origin resource. It's possible that sensitive information could
be revealed in the XMLHttpRequest response. (CVE-2008-5506)

Chris Evans discovered that Firefox did not properly protect a user's
data when accessing a same-domain JavaScript URL that is redirected to
an unparsable JavaScript off-site resource. If a user were tricked
into opening a malicious website, an attacker may be able to steal a
limited amount of private data. (CVE-2008-5507)

Chip Salzenberg, Justin Schuh, Tom Cross, and Peter William discovered
Firefox did not properly parse URLs when processing certain control
characters. (CVE-2008-5508)

Kojima Hajime discovered that Firefox did not properly handle an
escaped null character. An attacker may be able to exploit this flaw
to bypass script sanitization. (CVE-2008-5510)

Several flaws were discovered in the JavaScript engine. If a user were
tricked into opening a malicious website, an attacker could exploit
this to execute arbitrary JavaScript code within the context of
another website or with chrome privileges. (CVE-2008-5511,
CVE-2008-5512)

Flaws were discovered in the session-restore feature of Firefox. If a
user were tricked into opening a malicious website, an attacker could
exploit this to perform cross-site scripting attacks or execute
arbitrary JavaScript code with chrome privileges. (CVE-2008-5513).

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.
