7561eab8e8 zlib: backport fix for heap-based buffer over-read (CVE-2022-37434)
zlib through 1.2.12 has a heap-based buffer over-read or buffer overflow
in inflate in inflate.c via a large gzip header extra field. NOTE: only
applications that call inflateGetHeader are affected. Some common
applications bundle the affected zlib source code but may be unable to
call inflateGetHeader.

Fixes: CVE-2022-37434
