Ubuntu Security Notice (C) 2007-2016 Canonical, Inc. / NASL script (C) 2007-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

Various flaws were discovered in the layout and JavaScript engines. By
tricking a user into opening a malicious web page, an attacker could
execute arbitrary code with the user's privileges. (CVE-2007-5336,
CVE-2007-5339, CVE-2007-5340)

Michal Zalewski discovered that the onUnload event handlers were
incorrectly able to access information outside the old page content. A
malicious website could exploit this to modify the contents, or steal
confidential data (such as passwords), of the next loaded web page.
(CVE-2007-1095)

Stefano Di Paola discovered that Firefox did not correctly request
Digest Authentications. A malicious website could exploit this to
inject arbitrary HTTP headers or perform session splitting attacks
against proxies. (CVE-2007-2292)

Flaws were discovered in the file upload form control. By tricking a
user into opening a malicious web page, an attacker could force
arbitrary files from the user's computer to be uploaded without their
consent. (CVE-2006-2894, CVE-2007-3511)

Eli Friedman discovered that XUL could be used to hide a window's
titlebar. A malicious website could exploit this to enhance their
attempts at creating phishing websites. (CVE-2007-5334)

Georgi Guninski discovered that Firefox would allow file-system based
web pages to access additional files. By tricking a user into opening
a malicious web page from a gnome-vfs location, an attacker could
steal arbitrary files from the user's computer. (CVE-2007-5337)

It was discovered that the XPCNativeWrappers were not safe in certain
situations. By tricking a user into opening a malicious web page, an
attacker could run arbitrary JavaScript with the user's privileges.
(CVE-2007-5338).
