For adding to oss-fuzz, is there a contact email we can use that is connected to a google account? I am tempted to just put gregory.p.smith on there if not. :) I can volunteer to fuzz some interesting subset of the stdlib. The list I've come up with (by counting uses in my code) is: the XML parser (which seems to be written in C) struct (unpack) the various builtins that parse strings (like int()) hashlib binascii datetime's parsing json I'd also suggest the ast module, since people do use ast.literal_eval on untrusted strings, but I probably won't do that one myself. I wrote a fuzz test for json via upstream simplejson, but the bug on github is getting stale: https://github.com/simplejson/simplejson/issues/163 Should I add it to CPython instead? > We should investigate creating fuzz targets for the Python re module (_sre.c) > at a minimum. If we prioritize based on security risk, I'd argue that this is lower priority than things like json's speedup extension module, because people should generally not pass untrusted strings to the re module: it's very easy to DOS a service with regexes unless you're using RE2 or similar -- which is fuzzed. In contrast, json is supposed to accept untrusted input and people do that very often. (OTOH, I would be willing to bet that fuzzing re will yield more bugs than fuzzing json.) ---------- nosy: +Devin Jeanpierre _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue29505> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
