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:

Armin Razmdjou discovered that contents of locally readable files could
be made available via manipulation of form autocomplete 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 obtain sensitive information. (CVE-2015-0822)

Abhishek Arya discovered an out-of-bounds read and write when rendering
SVG content 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 obtain sensitive information. (CVE-2015-0827)

Paul Bandha discovered a use-after-free in IndexedDB. If a user were
tricked in to opening a specially crafted message with scripting enabled,
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-2015-0831)

Carsten Book, Christoph Diehl, Gary Kwong, Jan de Mooij, Liz Henry, Byron
Campen, Tom Schuster, and Ryan VanderMeulen 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-2015-0836)

Update instructions:

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