NVD Description

Note: Versions mentioned in the description apply only to the upstream libpython3_6m1_0 package and not the libpython3_6m1_0 package as distributed by SLES. See How to fix? for SLES:15.0 relevant fixed versions and status.

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.
