CVE-2012-3449
First published: Thu Aug 02 2012(Updated: )
Andreas Beckmann debian reports: openvswitch-pki creates the following world writable directories during installation: drwx-wx-wx 2 root root 40 Aug 1 05:32 /var/lib/openvswitch/pki/controllerca/incoming drwx-wx-wx 2 root root 40 Aug 1 05:32 /var/lib/openvswitch/pki/switchca/incoming Even if an ordinary local user cannot list the contents of the directory, he may correctly derive/guess filenames (unless they are exclusively $(mktemp)) and delete and replace files in there. I don't know how openvswitch-pki works, how it uses this directory, what probelms could possibly arise out of this.
