NVD Description

Note: Versions mentioned in the description apply only to the upstream zlib package and not the zlib package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2 relevant fixed versions and status.

zlib before 1.2.12 allows memory corruption when deflating (i.e., when compressing) if the input has many distant matches.
