 > Fixes the following security issues:
 > CVE-2022-1271: arbitrary-file-write vulnerability

 > zgrep applied to a crafted file name with two or more newlines
 > can no longer overwrite an arbitrary, attacker-selected file.
 > [bug introduced in gzip-1.3.10]


 > Other changes:

 > ** Changes in behavior

 >   'gzip -l' no longer misreports file lengths 4 GiB and larger.
 >   Previously, 'gzip -l' output the 32-bit value stored in the gzip
 >   header even though that is the uncompressed length modulo 2**32.
 >   Now, 'gzip -l' calculates the uncompressed length by decompressing
 >   the data and counting the resulting bytes.  Although this can take
 >   much more time, nowadays the correctness pros seem to outweigh the
 >   performance cons.

 >   'zless' is no longer installed on platforms lacking 'less'.

 > ** Bug fixes

 >   zgrep now names input file on error instead of mislabeling it as
 >   "(standard input)", if grep supports the GNU -H and --label options.

 >   'zdiff -C 5' no longer misbehaves by treating '5' as a file name.
 >   [bug present since the beginning]

 >   Configure-time options like --program-prefix now work.

 > Release Announcement:
