https://notcve.org/view.php?id=CVE-2012-2690

virt-edit in libguestfs before 1.18.0 does not preserve the permissions from the original file and saves the new file with world-readable permissions when editing, which might allow local guest users to obtain sensitive information. virt-edit de libguestfs anteriores a 1.18.0 no conserva los permisos del archivo original y guarda el nuevo fichero con permisos de lectura para otros al editar, lo que puede permitir a usuarios locales inviados obtener información confidencial. • http://rhn.redhat.com/errata/RHSA-2012-0774.html http://secunia.com/advisories/49431 http://secunia.com/advisories/49545 http://www.securityfocus.com/bid/53932 https://exchange.xforce.ibmcloud.com/vulnerabilities/76220 https://www.redhat.com/archives/libguestfs/2012-May/msg00104.html https://access.redhat.com/security/cve/CVE-2012-2690 https://bugzilla.redhat.com/show_bug.cgi?id=831117 • CWE-255: Credentials Management Errors •
