Ubuntu 6.06 LTS / 7.04 / 7.10 / 8.04 LTS : mozilla-thunderbird, thunderbird vulnerabilities (USN-629-1)

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


Synopsis :

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

Description :

Various flaws were discovered in the browser engine. If a user had
JavaScript enabled and were tricked into opening a malicious web page,
an attacker could cause a denial of service via application crash, or
possibly execute arbitrary code with the privileges of the user
invoking the program. (CVE-2008-2798, CVE-2008-2799)

It was discovered that Thunderbird would allow non-privileged XUL
documents to load chrome scripts from the fastload file if JavaScript
was enabled. This could allow an attacker to execute arbitrary
JavaScript code with chrome privileges. (CVE-2008-2802)

A flaw was discovered in Thunderbird that allowed overwriting trusted
objects via mozIJSSubScriptLoader.loadSubScript(). If a user had
JavaScript enabled and was tricked into opening a malicious web page,
an attacker could execute arbitrary code with the privileges of the
user invoking the program. (CVE-2008-2803)

Daniel Glazman found that an improperly encoded .properties file in an
add-on can result in uninitialized memory being used. If a user were
tricked into installing a malicious add-on, Thunderbird may be able to
see data from other programs. (CVE-2008-2807)

John G. Myers discovered a weakness in the trust model used by
Thunderbird regarding alternate names on self-signed certificates. If
a user were tricked into accepting a certificate containing alternate
name entries, an attacker could impersonate another server.
(CVE-2008-2809)

A vulnerability was discovered in the block reflow code of
Thunderbird. If a user enabled JavaScript, this vulnerability could be
used by an attacker to cause a denial of service via application
crash, or execute arbitrary code with the privileges of the user
invoking the program. (CVE-2008-2811)

A flaw was discovered in the browser engine. A variable could be made
to overflow causing Thunderbird to crash. If a user enable JavaScript
and was tricked into opening a malicious web page, an attacker could
cause a denial of service or possibly execute arbitrary code with the
privileges of the user invoking the program. (CVE-2008-2785)

Mozilla developers audited the MIME handling code looking for similar
vulnerabilities to the previously fixed CVE-2008-0304, and changed
several function calls to use safer versions of string routines.

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.

Risk factor :

Critical / CVSS Base Score : 10.0
(CVSS2#AV:N/AC:L/Au:N/C:C/I:C/A:C)
CVSS Temporal Score : 7.8
(CVSS2#E:POC/RL:OF/RC:C)
Public Exploit Available : true
