Ubuntu 8.04 LTS / 8.10 / 9.04 : firefox-3.0, xulrunner-1.9 vulnerabilities (USN-821-1)

Ubuntu Security Notice (C) 2009-2016 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 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).

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.
