Description

This security bulletin contains information about 1 vulnerability.


1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2012-3449)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote non-authenticated attacker to manipulate or delete data.

Open vSwitch 1.4.2 uses world writable permissions for (1) /var/lib/openvswitch/pki/controllerca/incoming/ and (2) /var/lib/openvswitch/pki/switchca/incoming/, which allows local users to delete and overwrite arbitrary files.
