Open Networking Foundation · Openvswitch · CVE-2012-3449
**Name of the Vulnerable Software and Affected Versions**
Open vSwitch version 1.4.2
**Description**
The issue allows local users to delete and overwrite arbitrary files due to world-writable permissions for certain directories. Specifically, the directories `/var/lib/openvswitch/pki/controllerca/incoming/` and `/var/lib/openvswitch/pki/switchca/incoming/` have insecure permissions.
**Recommendations**
For Open vSwitch version 1.4.2, consider changing the permissions of the `/var/lib/openvswitch/pki/controllerca/incoming/` and `/var/lib/openvswitch/pki/switchca/incoming/` directories to prevent world-writable access, thereby restricting the ability of local users to delete or overwrite files in these directories.
