Martin Panter added the comment: Klamann, thanks for crash report. I think your decompress crash is explained by the bug expanding past UINT_MAX I identified above. The key is that length = 0 in zlib_Decompress_decompress_impl(), as if wrapped around, and the return value will have been resized to zero. My suggested fix step 7 would address this.
The workaround here would either be to pass compressed data in smaller chunks (4 MB or less), so that no chunk can expand to 4 GiB, or to make use of the max_length parameter. Either way, it will make any code more complicated though. If anyone wants to write a patch (or do testing) to solve any or all of the problems, I am happy to help. But it is not a high priority for me to do all the work, because I am not set up to test it easily. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue27130> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
