This suggests an important point: CVEs could potentially be tracked by
Adobe, and thus have a relationship to systems on which the CVEs
aren't directly important to vulnerability assessment of a package
with something like pcre or libpcre in its name.

"pcre_compile.cpp" in
https://code.google.com/p/google-security-research/issues/detail?id=208
might indicate that Adobe has a fork.
http://vcs.pcre.org/pcre/code/trunk/ has the pcre_compile.c filename,
and http://vcs.pcre.org/pcre2/code/trunk/src/ has the pcre2_compile.c
filename.

JavaScript may be "something else" in most cases, e.g.,

  http://blog.chromium.org/2009/02/irregexp-google-chromes-new-regexp.html
  https://github.com/v8/v8/tree/master/src/regexp
  https://hg.mozilla.org/mozilla-central/file/tip/js/src/irregexp

We haven't looked at whether there are ever attack vectors associated
with untrusted Lua code, e.g., if the Lua code can make use of
something like https://github.com/rrthomas/lrexlib to reach vulnerable
code found in the system's libpcre package.
