NVD Description

Note: Versions mentioned in the description apply only to the upstream libz1-32bit package and not the libz1-32bit package as distributed by SLES. See How to fix? for SLES:15.2 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.
