Subject: CVE Request: heap overflow in Python zipimport module
Hello.
In Python zipimport module,
if compress != 0, then bytes_size = data_size + 1
data_size is not sanitized, so if data_size = -1,
then it overflows and becomes 0.
In that case, python allocates small heap, but after that in freed, it
overflows heap.
Fix info https://bugs.python.org/issue26171
Please help assign a CVE to this vulnerability.
Thank you.
