CVE-2023-46345 (https://gist.github.com/rycbar77/d747b2c37b544ece30b2353a65ab41f9):

Catdoc v0.95 was discovered to contain a NULL pointer dereference via the component xls2csv at src/xlsparse.c.

No evidence of an upstream report or fix, while apparently the
upstream bug tracker and wiki are broken, and no update since
2016. Time for last rites?
