In general, these flaws cannot be exploited through email in the Thunderbird product because scripting is disabled when reading mail, but are potentially risks in browser or browser-like contexts.

CVE-2017-5398: Memory safety bugs fixed in Thunderbird 45.8 (critical)
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-2017-5400: asm.js JIT-spray bypass of ASLR and DEP (critical)
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-2017-5401: Memory Corruption when handling ErrorResult (critical)
A crash triggerable by web content in which an <code>ErrorResult</code> references unassigned memory due to a logic error. The resulting crash may be exploitable.
CVE-2017-5402: Use-after-free working with events in FontFace objects (critical)
A use-after-free can occur when events are fired for a <code>FontFace</code> object after the object has been already been destroyed while working with fonts. This results in a potentially exploitable crash.
CVE-2017-5404: Use-after-free working with ranges in selections (critical)
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-2017-5405: FTP response codes can cause use of uninitialized values for ports (low)
Certain response codes in FTP connections can result in the use of uninitialized values for ports in FTP operations.
CVE-2017-5407: Pixel and history stealing via floating-point timing side channel with SVG filters (high)
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-2017-5408: Cross-origin reading of video captions in violation of CORS (moderate)
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-2017-5410: Memory corruption during JavaScript garbage collection incremental sweeping (high)
Memory corruption resulting in a potentially exploitable crash during garbage collection of JavaScript due errors in how incremental sweeping is managed for memory cleanup.
