Summary
=======

The package thunderbird before version 45.7.0-1 is vulnerable to
multiple issues including arbitrary code execution, information
disclosure, privilege escalation and content spoofing.

Resolution
==========

Upgrade to 45.7.0-1.

# pacman -Syu "thunderbird>=45.7.0-1"

The problems have been fixed upstream in version 45.7.0.

Workaround
==========

None.

Description
===========

- CVE-2017-5373 (arbitrary code execution)

Several memory safety bugs have been found in Firefox < 51 and
Thunderbird < 47.5. Some of these bugs showed evidence of memory
corruption and we presume that with enough effort that some of these
could be exploited to run arbitrary code.

- CVE-2017-5375 (arbitrary code execution)

JIT code allocation in Firefox < 51 and Thunderbird < 45.7 can allow
for a bypass of ASLR and DEP protections leading to potential memory
corruption attacks.

- CVE-2017-5376 (arbitrary code execution)

A use-after-free vulnerability has been found in Firefox < 51 and
Thunderbird < 45.7, while manipulating XSL in XSLT documents.

- CVE-2017-5378 (information disclosure)

An information disclosure vulnerability has been found in Firefox < 51
and Thunderbird < 45.7, where hashed codes of JavaScript objects are
shared between pages. This allows for pointer leaks because an object’s
address can be discovered through hash codes, and also allows for data
leakage of an object’s content using these hash codes.

- CVE-2017-5380 (arbitrary code execution)

A potential use-after-free vulnerability during DOM manipulation of SVG
content has been in Firefox < 51 and Thunderbird < 45.7.

- CVE-2017-5383 (content spoofing)

URLs containing certain unicode glyphs for alternative hyphens and
quotes do not properly trigger punycode display in Firefox < 51 and
Thunderbird < 45.7, allowing for domain name spoofing attacks in the
location bar.

- CVE-2017-5390 (privilege escalation)

The JSON viewer in the Developer Tools in Firefox < 51 and Thunderbird
< 45.7 uses insecure methods to create a communication channel for
copying and viewing JSON or HTTP headers data, allowing for potential
privilege escalation.

- CVE-2017-5396 (arbitrary code execution)

A use-after-free vulnerability has been found in the Media Decoder of
Firefox < 51 and Thunderbird < 45.7, when working with media files when
some events are fired after the media elements are freed from memory.

Impact
======

A remote attacker can access sensitive information, spoof content,
escalate privileges and execute arbitrary code on the affected host.
