You can looked at the sources:
$ head -12 /usr/src/lib/libz/ChangeLog
ChangeLog file for zlib
Changes in 1.1.4 (11 March 2002)
- ZFREE was repeated on same allocation on some error conditions.

- Returned incorrect error (Z_MEM_ERROR) on some invalid data
- Avoid accesses before window for invalid distances with inflate
window less than 32K.
