Comment 1 Gabriele Sonnu 2022-02-18 16:08:22 UTC

I was able to reproduce it on:

 - SUSE:SLE-12:Update/unzip       6.00
 - SUSE:SLE-15:Update/unzip       6.00
 - openSUSE:Factory/unzip         6.00

Not sure about:

 - SUSE:SLE-11-SP1:Update/unzip   5.52
 - SUSE:SLE-11-SP2:Update/unzip   6.00

I'd say they are affected too but please double check.
No patch available for now.

Fix missing in unzip-rcc, pre-checkin was not run. Should be singlespec!
