@ -39,7 +39,11 @@ Version 1.6.20beta03 [November 25, 2015]
Version 1.6.20rc01 [November 25, 2015]
Fixed an error in handling of bad zlib CMINFO field, found by American
Fuzzy Lop.
Fuzzy Lop, reported by Brian Carpenter. inflate() doesn't immediately
fault a bad CMINFO field; instead a 'too far back' error happens later
(at least some times). pngfix failed to limit CMINFO to the allowed
values but then assumed that window_bits was in range, triggering an
assert. The bug is mostly harmless; the file can't be fixed.
