Subject: [Buildroot] [PATCH 1/2] package/gzip: security bump to 1.12
Date: Tue, 19 Apr 2022 13:17:13 +0200	[thread overview]
Message-ID: <20220419111714.1647112-1-marcus.hoffmann@othermo.de> (raw)

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]

https://www.openwall.com/lists/oss-security/2022/04/07/8

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.
