JIT-spray targeting asm.js combined with a heap spray allows for a bypass
of ASLR and DEP protections leading to potential memory corruption
attacks. (CVE-2017-5400)

A crash triggerable by web content in which an ErrorResult references
unassigned memory due to a logic error. The resulting crash may be
exploitable. (CVE-2017-5401)

A use-after-free can occur when events are fired for a FontFace object
after the object has been already been destroyed while working with fonts.
This results in a potentially exploitable crash. (CVE-2017-5402)

A use-after-free error can occur when manipulating ranges in selections
with one node inside a native anonymous tree and one node outside of it.
This results in a potentially exploitable crash. (CVE-2017-5404)

Using SVG filters that don't use the fixed point math implementation on a
target iframe, a malicious page can extract pixel values from a targeted
user. This can be used to extract history information and read text values
across domains. This violates same-origin policy and leads to information
disclosure. (CVE-2017-5407)

Memory corruption resulting in a potentially exploitable crash during
garbage collection of JavaScript due errors in how incremental sweeping is
managed for memory cleanup. (CVE-2017-5410)

Video files loaded video captions cross-origin without checking for the
presence of CORS headers permitting such cross-origin use, leading to
potential information disclosure for video captions. (CVE-2017-5408)

Certain response codes in FTP connections can result in the use of
uninitialized values for ports in FTP operations. (CVE-2017-5405)

Mozilla developers and community members Boris Zbarsky, Christian Holler,
Honza Bambas, Jon Coppeard, Randell Jesup, André Bargull, Kan-Ru Chen, and
Nathan Froyd reported memory safety bugs present in Thunderbird 45.7. 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-2017-5398)
