Package: zstd Version: 1.3.1+dfsg-2 `zstd -t` has a bug that changes the permissions of /dev/null when run as root:
https://github.com/facebook/zstd/issues/851 With zstd 1.3.1+dfsg-2: root@unstable:~# cd /tmp root@unstable:/tmp# cp /etc/passwd ./ root@unstable:/tmp# zstd passwd passwd : 39.07% ( 2004 => 783 bytes, passwd.zst) root@unstable:/tmp# ls -l /dev/null crw-rw-rw- 1 root root 1, 3 Nov 8 09:12 /dev/null root@unstable:/tmp# zstd -t passwd.zst passwd.zst : 2004 bytes root@unstable:/tmp# ls -l /dev/null crw-r--r-- 1 root root 1, 3 Nov 8 09:15 /dev/null Upstream's 1.3.2 fixes this issue. Best regards, Ivan
