Ubuntu Security Notice 2552-1 - Olli Pettay and Boris Zbarsky discovered an issue during anchor navigations in some circumstances. If a user were tricked in to opening a specially crafted message with scripting enabled, an attacker could potentially exploit this to bypass same-origin policy restrictions. Christoph Kerschbaumer discovered that CORS requests from navigator.sendBeacon() followed 30x redirections after preflight. If a user were tricked in to opening a specially crafted message with scripting enabled, an attacker could potentially exploit this to conduct cross-site request forgery (XSRF) attacks. Various other issues were also addressed.

thunderbird vulnerabilities
============================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 14.10
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS

Summary:

Several security issues were fixed in Thunderbird.

Software Description:
- thunderbird: Mozilla Open Source mail and newsgroup client

Details:

Olli Pettay and Boris Zbarsky discovered an issue during anchor
navigations in some circumstances. If a user were tricked in to opening
a specially crafted message with scripting enabled, an attacker could
potentially exploit this to bypass same-origin policy restrictions.
(CVE-2015-0801)

Christoph Kerschbaumer discovered that CORS requests from
navigator.sendBeacon() followed 30x redirections after preflight. If a
user were tricked in to opening a specially crafted message with
scripting enabled, an attacker could potentially exploit this to conduct
cross-site request forgery (XSRF) attacks. (CVE-2015-0807)

Aki Helin discovered a use-after-free when playing MP3 audio files using
the Fluendo MP3 GStreamer plugin in certain circumstances. If a user were
tricked in to opening a specially crafted message, an attacker could
potentially exploit this to cause a denial of service via application
crash, or execute arbitrary code with the privileges of the user invoking
Thunderbird. (CVE-2015-0813)

Christian Holler, Steve Fink, and Byron Campen discovered multiple memory
safety issues in Thunderbird. If a user were tricked in to opening a
specially crafted message with scripting enabled, an attacker could
potentially exploit these to cause a denial of service via application
crash, or execute arbitrary code with the privileges of the user invoking
Thunderbird. (CVE-2015-0815)

Mariusz Mlynski discovered that documents loaded via resource: URLs (such
as PDF.js) could load privileged chrome pages. If a user were tricked in
to opening a specially crafted message with scripting enabled, an attacker
could potentially exploit this in combination with another flaw, in order
to execute arbitrary script in a privileged context. (CVE-2015-0816)

Update instructions:

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

Ubuntu 14.10:
thunderbird 1:31.6.0+build1-0ubuntu0.14.10.1

Ubuntu 14.04 LTS:
thunderbird 1:31.6.0+build1-0ubuntu0.14.04.1

Ubuntu 12.04 LTS:
thunderbird 1:31.6.0+build1-0ubuntu0.12.04.1

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