Ubuntu Security Notice (C) 2009-2013 Canonical, Inc. / NASL script (C) 2009-2013 Tenable Network Security, Inc.


Synopsis :

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

Description :

Several flaws were discovered in the Firefox browser and JavaScript
engines. If a user were tricked into viewing a malicious website, a
remote attacker could cause a denial of service or possibly execute
arbitrary code with the privileges of the user invoking the program.
(CVE-2009-3070, CVE-2009-3071, CVE-2009-3072, CVE-2009-3074,
CVE-2009-3075)

Jesse Ruderman and Dan Kaminsky discovered that Firefox did not
adequately inform users when security modules were added or removed
via PKCS11. If a user visited a malicious website, an attacker could
exploit this to trick the user into installing a malicious PKCS11
module. (CVE-2009-3076)

It was discovered that Firefox did not properly manage memory when
using XUL tree elements. If a user were tricked into viewing a
malicious website, a remote attacker could cause a denial of service
or possibly execute arbitrary code with the privileges of the user
invoking the program. (CVE-2009-3077)

Juan Pablo Lopez Yacubian discovered that Firefox did properly display
certain Unicode characters in the location bar and other text fields
when using a certain non-Ubuntu font. If a user configured Firefox to
use this font, an attacker could exploit this to spoof the location
bar, such as in a phishing attack. (CVE-2009-3078)

It was discovered that the BrowserFeedWriter in Firefox could be
subverted to run JavaScript code from web content with elevated chrome
privileges. If a user were tricked into viewing a malicious website,
an attacker could exploit this to execute arbitrary code with the
privileges of the user invoking the program. (CVE-2009-3079).

Solution :

Update the affected packages.
