CVE-2019-17514 Information

Description

library/glob.html in the Python 2 and 3 documentation before 2016 has potentially misleading information about whether sorting occurs as demonstrated by irreproducible cancer-research results. NOTE: the effects of this documentation cross application domains and thus it is likely that security-relevant code elsewhere is affected. This issue is not a Python implementation bug and there are no reports that NMR researchers were specifically relying on library/glob.html. In other words because the older documentation stated \finds all the pathnames matching a specified pattern according to the rules used by the Unix shell\ one might have incorrectly inferred that the sorting that occurs in a Unix shell also occurred for glob.glob. There is a workaround in newer versions of Willoughby nmr-data_compilation-p2.py and nmr-data_compilation-p3.py which call sort() directly.
