CVE-2018-14647

Priority
Description
Python's elementtree C accelerator failed to initialise Expat's hash salt
during initialization. This could make it easy to conduct denial of service
attacks against Expat by constructing an XML document that would cause
pathological hash collisions in Expat's internal data structures, consuming
large amounts CPU and RAM. Python 3.8, 3.7, 3.6, 3.5, 3.4, 2.7 are believed
to be vulnerable.
