How to fix?

There is no fixed version for Echo:latest libtext-csv-xs-perl.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libtext-csv-xs-perl package and not the libtext-csv-xs-perl package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

Text::CSV_XS versions before 1.65 for Perl allow quadratic CPU use by copying the unparsed remainder per record of CR-only input in getline.

With eol unset, the default, getline reads with Perl's default line separator, so input with CR-only line endings arrives as one chunk. After each record the parser copies the whole unparsed remainder into a new buffer, which the next call parses and copies again, so the work grows with the square of the input size.

A reader with default options that is sent CSV with classic Mac line endings spends seconds of CPU time on a megabyte of input.
