- update to 1.12 (CVE-2022-1271,bsc#1198062):
* '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'.
* 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]
* 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.
* Configure-time options like --program-prefix now work.
- refresh zdiff.diff, zgrep.diff, zmore.diff
