Comment (by arthuredelstein):

 In trying to apply [https://gitweb.torproject.org/tor-
 browser.git/commit/b1f011d993b4a00db2cb50c49dea38ec5188fdb0 "Backport two
 integer overflow patches], I found that the [https://gitweb.torproject.org
 /tor-
 browser.git/blobdiff/3b338aadd92ac0c3d9584fceea28f8934cdf20f0..b1f011d993b4a00db2cb50c49dea38ec5188fdb0:/js/src/vm
 /Interpreter-inl.h part in Interpreter-inl.h] doesn't apply to ESR31. The
 code in the Interpreter has changed substantially. I think that the
 current version of AddOperation does not protect overflow (which looks
 like a possible security regression for Mozilla), but it will require
 careful study to understand.

 The rest of the patch is [https://hg.mozilla.org/mozilla-
 central/rev/c00387255d25 already in ESR31].
