Comment 1 Marian Rehak 2020-02-04 15:38:29 UTC

Created texlive tracking bugs for this issue:

Affects: fedora-all [bug 1798119]

Comment 2 Marco Benatto 2020-02-26 19:40:13 UTC

Statement:

This flaw only affects the detex binary, which is not provided by any versions of texlive as shipped with Red Hat Enterprise Linux 7 and 8.

Comment 3 Marco Benatto 2020-02-26 19:42:59 UTC

Closing this flaw as NOTABUG as the affected function is only used within detex binary, which is not shipped with any RHEL's texlive version.
