Description Laura Pardo 2018-03-06 00:14:03 UTC

The packaging of NextCloud in openSUSE used /srv/www/htdocs in an unsafe manner, which could have allowed scripts running as wwwrun user to escalate privileges to root during nextcloud package upgrade.

Comment 1 Laura Pardo 2018-03-06 00:14:23 UTC

Created nextcloud tracking bugs for this issue:

Affects: fedora-all [bug 1551803]
Affects: epel-7 [bug 1551802]

Comment 2 Christian Glombek 2018-03-06 12:02:53 UTC

Do I correctly assume this only affects the SUSE rpm and does not affect the nexctloud rpm in the Fedora repos?

Correct, this is relevant to the nextcloud packaging in openSUSE.
