"- Fix heap-buffer-overrun with --one-top-level. - Support for zstd compression. - The -K option interacts properly with member names given in the command line. - Fix CVE-2018-20482"
This patch was reverted because 'tar 1.31' crashed when installing PakFire packages with the option '--no-overwrite-dir'. See: https://bugzilla.ipfire.org/show_bug.cgi?id=11958
Included is now a patch from https://savannah.gnu.org/bugs/?55413, which seems to fix this issue. The test cases given in https://savannah.gnu.org/bugs/?55413#comment1 ran without problems.
As always, please check and confirm.
Best, Matthias
