CVSS: 7.5EPSS: 1%CPEs: 16EXPL: 0CVE-2018-14647 – python: Missing salt initialization in _elementtree.c module
https://notcve.org/view.php?id=CVE-2018-14647
25 Sep 2018 — 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. The vulnerability exists in Python versions 3.7.0, 3.6.0 through 3.6.6, 3.5.0 through 3.5.6, 3.4.0 through 3.4.9, 2.7.0 through 2.7.15.
