Ubuntu Security Notice USN-930-6 July 26, 2010
firefox, firefox-3.0, xulrunner-1.9.2 vulnerability
CVE-2010-2755
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 9.04
Ubuntu 9.10

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 9.04:
abrowser 3.6.8+build1+nobinonly-0ubuntu0.9.04.1
firefox-3.0 3.6.8+build1+nobinonly-0ubuntu0.9.04.1
xulrunner-1.9.2 1.9.2.8+build1+nobinonly-0ubuntu0.9.04.1

Ubuntu 9.10:
abrowser 3.6.8+build1+nobinonly-0ubuntu0.9.10.1
firefox-3.5 3.6.8+build1+nobinonly-0ubuntu0.9.10.1
xulrunner-1.9.2 1.9.2.8+build1+nobinonly-0ubuntu0.9.10.1

After a standard system upgrade you need to restart Firefox and any
applications that use Xulrunner to effect the necessary changes.

Details follow:

USN-957-1 fixed vulnerabilities in Firefox and Xulrunner. Daniel Holbert
discovered that the fix for CVE-2010-1214 introduced a regression which did
not properly initialize a plugin pointer. If a user were tricked into
viewing a malicious site, a remote attacker could use this to crash the
browser or run arbitrary code as the user invoking the program.
(CVE-2010-2755)

This update fixes the problem.

Original advisory details:

If was discovered that Firefox could be made to access freed memory. If a
user were tricked into viewing a malicious site, a remote attacker could
cause a denial of service or possibly execute arbitrary code with the
privileges of the user invoking the program. This issue only affected
Ubuntu 8.04 LTS. (CVE-2010-1121)

Several flaws were discovered in the browser engine of Firefox. If a
user were tricked into viewing a malicious site, a remote attacker could
cause a denial of service or possibly execute arbitrary code with the
privileges of the user invoking the program. (CVE-2010-1200, CVE-2010-1201,
CVE-2010-1202, CVE-2010-1203)

A flaw was discovered in the way plugin instances interacted. An attacker
could potentially exploit this and use one plugin to access freed memory from a
second plugin to execute arbitrary code with the privileges of the user
invoking the program. (CVE-2010-1198)

An integer overflow was discovered in Firefox. If a user were tricked into
viewing a malicious site, an attacker could overflow a buffer and cause a
denial of service or possibly execute arbitrary code with the privileges of
the user invoking the program. (CVE-2010-1196)

Martin Barbella discovered an integer overflow in an XSLT node sorting
routine. An attacker could exploit this to overflow a buffer and cause a
denial of service or possibly execute arbitrary code with the privileges of
the user invoking the program. (CVE-2010-1199)

Michal Zalewski discovered that the focus behavior of Firefox could be
subverted. If a user were tricked into viewing a malicious site, a remote
attacker could use this to capture keystrokes. (CVE-2010-1125)

Ilja van Sprundel discovered that the ‘Content-Disposition: attachment’
HTTP header was ignored when ‘Content-Type: multipart’ was also present.
Under certain circumstances, this could potentially lead to cross-site
scripting attacks. (CVE-2010-1197)

Amit Klein discovered that Firefox did not seed its random number generator
often enough. An attacker could exploit this to identify and track users
across different web sites. (CVE-2008-5913)

===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 10.04 LTS

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 10.04 LTS:
thunderbird 3.0.6+build2+nobinonly-0ubuntu0.10.04.1

After a standard system update you need to restart Thunderbird to make
all the necessary changes.

Details follow:

Several flaws were discovered in the browser engine of Thunderbird. If a
user were tricked into viewing malicious content, a remote attacker could
use this to crash Thunderbird or possibly run arbitrary code as the user
invoking the program. (CVE-2010-1211, CVE-2010-1212)

An integer overflow was discovered in how Thunderbird processed CSS values.
An attacker could exploit this to crash Thunderbird or possibly run
arbitrary code as the user invoking the program. (CVE-2010-2752)

An integer overflow was discovered in how Thunderbird interpreted the XUL
element. If a user were tricked into viewing malicious content, a remote
attacker could use this to crash Thunderbird or possibly run arbitrary code
as the user invoking the program. (CVE-2010-2753)

Aki Helin discovered that libpng did not properly handle certain malformed
PNG images. If a user were tricked into opening a crafted PNG file, an
attacker could cause a denial of service or possibly execute arbitrary code
with the privileges of the user invoking the program. (CVE-2010-1205)

Yosuke Hasegawa discovered that the same-origin check in Thunderbird could
be bypassed by utilizing the importScripts Web Worker method. If a user
were tricked into viewing malicious content, an attacker could exploit this
to read data from other domains. (CVE-2010-1213)

Chris Evans discovered that Thunderbird did not properly process improper
CSS selectors. If a user were tricked into viewing malicious content, an
attacker could exploit this to read data from other domains.
(CVE-2010-0654)

Soroush Dalili discovered that Thunderbird did not properly handle script
error output. An attacker could use this to access URL parameters from
other domains. (CVE-2010-2754)
