Hi Tej,

Sorry---could you explain what the neuro-sig needs to do here? I checked and we don't maintain libtiff as one of our group packages. Are some of our packages affected by this too?

Cheers,
Comment 3 TEJ RATHI 2022-03-15 09:30:02 UTC 
Hello Ankur,

neuro-sig is CC'd into this automatically by Bugzilla, when I created this flaw bug. Libtiff is only affected. Just ignore this if it isn't related to you. Sorry for the noise in your inbox.

Thank you.

Thanks, I'll remove us from the CC list otherwise it'll keep being listed in our bugs and cause confusion.
