Hi Aleksandr  :)



Please add a comment to that bug to request resolution of the issue.

Alternatively you (and anyone else) can just delete gif2tiff

Unfortunately you are yet one more example of a user that's been left in

they can resolve or mitigate this vulnerability. Our apologies.

Hope that helps.
