Update to 52.4.0

Chagelog:
New
In Thunderbird 52 a new behavior was introduced for replies to mailing
list posts: "When replying to a mailing list, reply will be sent to
address in From header ignoring Reply-to header". A new preference
mail.override_list_reply_to allows to restore the previous behavior.

Fixed
Under certain circumstances (image attachment and non-image attachment),
attached images were shown truncated in messages stored in IMAP
folders not synchronised for offline use.

Fixed
IMAP UIDs > 0x7FFFFFFF not handled properly

A use-after-free vulnerability can occur in the Fetch API when the
worker or the associated window are freed when still in use,
resulting in a potentially exploitable crash.

Description

A use-after-free vulnerability can occur in design mode when image
objects are resized if objects referenced during the resizing have
been freed from memory. This results in a potentially exploitable crash.

#CVE-2017-7824: Buffer overflow when drawing and validating elements
with ANGLE

Reporter
    Omair, Andre Weissflog
Impact
    high

Description

A buffer overflow occurs when drawing and validating elements with
the ANGLE graphics library, used for WebGL content. This is due to
an incorrect value being passed within the library during checks and
results in a potentially exploitable crash.

#CVE-2017-7805: Use-after-free in TLS 1.2 generating handshake hashes

Reporter
    Martin Thomson
Impact
    high

Description

During TLS 1.2 exchanges, handshake hashes are generated which point
to a message buffer. This saved data is used for later messages but
in some cases, the handshake transcript can exceed the space available
in the current buffer, causing the allocation of a new buffer. This
leaves a pointer pointing to the old, freed buffer, resulting in
a use-after-free when handshake hashes are then calculated afterwards.
This can result in a potentially exploitable crash.

#CVE-2017-7814: Blob and data URLs bypass phishing and malware
protection warnings

Reporter
    Fran巽ois Marier
Impact
    moderate

Description

File downloads encoded with blob: and data: URL elements bypassed
normal file download checks though the Phishing and Malware Protection
feature and its block lists of suspicious sites and files. This
would allow malicious sites to lure users into downloading executables
that would otherwise be detected as suspicious.

#CVE-2017-7825: OS X fonts render some Tibetan and Arabic unicode
characters as spaces

Reporter
    Khalil Zhani
Impact
    moderate

Description

Several fonts on OS X display some Tibetan and Arabic characters
as whitespace. When used in the addressbar as part of an IDN
this can be used for domain name spoofing attacks.
Note: This attack only affects OS X operating systems. Other
operating systems are unaffected.

#CVE-2017-7823: CSP sandbox directive did not create a unique origin

Reporter
    Jun Kokatsu
Impact
    moderate

Description

The content security policy (CSP) sandbox directive did not
create a unique origin for the document, causing it to behave as
if the allow-same-origin keyword were always specified. This could
allow a Cross-Site Scripting (XSS) attack to be launched from
unsafe content.

#CVE-2017-7810: Memory safety bugs fixed in Firefox 56, Firefox ESR 52.4,
and Thunderbird 52.4

Reporter
    Mozilla developers and community
Impact
    critical

Description

Mozilla developers and community members Christoph Diehl, Jan de Mooij,
Jason Kratzer, Randell Jesup, Tom Ritter, Tyson Smith, and Sebastian
Hengst reported memory safety bugs present in Firefox 55, Firefox
ESR 52.3, and Thunderbird 52.3. 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.
