Description Iker Pedrosa 2021-11-04 12:12:59 UTC

+++ This bug was initially created as a clone of Bug #2018697 +++

Description of problem:
The useradd program fails to add users into a chroot.

Version-Release number of selected component (if applicable):
4.9

How reproducible:
Always

Steps to Reproduce:
1. rm -fr /tmp/newroot && mkdir -p /tmp/newroot/etc && cp -at /tmp/newroot/etc /etc/{passwd,group,sub[ug]id,gshadow,shadow,login.defs,default} 
2. useradd --prefix /tmp/newroot --groups=wheel --create-home --password= test_user 
free(): invalid pointer
Aborted (core dumped)

Actual results:
It aborts with "free(): invalid pointer".

Expected results:
It should add the user to /tmp/newroot/etc/passwd.

Additional info:
It is fixed upstream, so it could be backported: https://github.com/shadow-maint/shadow/issues/394

Apparently openSUSE hit this as well and backported the upstream commit: https://build.opensuse.org/package/view_file/openSUSE:Factory/shadow/shadow-fix-sigabrt.patch
