Looks like it is time to update zlib:

@https://zlib.net/

Version 1.2.12 has these key improvements over 1.2.11:

• Fix a deflate bug when using the Z_FIXED strategy that can result in out-of-bound accesses.
• Fix a deflate bug when the window is full in deflate_stored().
• Speed up CRC-32 computations by a factor of 1.5 to 3.
• Use the hardware CRC-32 instruction on ARMv8 processors.
• Speed up crc32_combine() with powers of x tables.
• Add crc32_combine_gen() and crc32_combine_op() for fast combines.

Due to the bug fixes, any installations of 1.2.11 should be replaced with 1.2.12.

Currently, we have 1.2.11-5 in Testing.
