Critical WordPress Vulnerability discovered

A critical security bug discovered in WordPress can cause an attacker to cripple not only your website, but the entire server your website resides on. This is due to the vulnerability in the PHP XML parser used by WordPress’ XMLRPC implementation.

This bug affects Drupal installations as well (Drupal 6 & 7)

A reasonably skilled attacker can exploit this bug and cause your server to run out of memory simply by sending a 200+ KB XML file.

This bug is critical enough to cause the security team at WordPress to backport the affected files to the earlier versions, i.e. WordPress 3.7 and WordPress 3.8

If you are currently running WP 3.7 or WP 3.8 branch, please update to the latest .4 version.

The following versions are patched against this security bug.
Wordpress 3.7.4
Wordpress 3.8.4
Wordpress 3.9.2

The following files are updated:

    If that holds true for the Colossal squid, this male specimen that was captured could very well be dwarfed by a much larger female of

    Hi! I know this is somewhat off topic but I was wondering which blog platform
    are you using for this website? I’m getting fed up of WordPress
    because I’ve had problems with hackers and I’m looking at options for another platform.

    I would be awesome if you could point me in the direction of a good platform.

    My blog has a lot of unique content I’ve either created myself or outsourced but it looks like a lot of it is popping it up all over the web without my agreement.
    Do you know any methods to help stop content
    from being ripped off? I’d truly appreciate it.

    Nevertheless think of if you added some great visuals

    site could certainly be one of the very best in its field.

    Querétaro, Qro.- Tras una carta enviada en enero al
    gobernador de Querétaro, el coordinador de comunicación social, Abel Ernesto Magaña Álvarez, rectificó su postura de cancelar
    a Libertad de Palabra la propuesta publicitaria que nuestro
    medio le hizo para este 2011.
    Abel Ernesto Magaña Álvarez

    Al parecer, en Gobierno Estatal aplican la frase “no pago para que me peguen”.
    Foto: Agencia SieteFoto.

    El anuncio de la cancelación de la propuesta publicitaria –que incluye otros
    servicios adicionales a los ofrecidos en 2010–, ocurrió unas horas después de
    publicar la nota titulada: “Los errores de Jorge García Quiroz”, quien era el secretario de gobierno.

    En la llamada se nos dijo que por órdenes de Abel Magaña Álvarez se nos informaba que nuestra propuesta publicitaria finalmente no sería aceptada al
    80%, como ya nos lo había informado el propio Abel,
    sino sólo al 20%, y que el trámite podría llevarse “varias semanas”.

    Así se le informó en carta al gobernador, José Eduardo Calzada Rovirosa, lo que al parecer derivó en que Magaña Álvarez rectificara,
    aunque nos aclaró que se tendría que hacer
    un convenio con el monto menor, similar a lo contratado en el 2010 (convenio 1), y otro adicional hasta
    alcanzar el monto acordado (convenio 2).

    Sin embargo, para no retrasar los pagos, Magaña Álvarez nos solicitó la factura de enero,
    misma que se entregó en su oficina el pasado 16 de enero, bajo el concepto: Según convenio publicitario 2011 (enero).

    Acto seguido, solicitó que pasáramos con Rocío, a la secretaría particular
    del gobernador (justo a un lado del despacho del mandatario), para recibir el pago, con la
    aclaración de que en breve firmaríamos el convenio
    al que hace referencia la factura.

    De manera “anormal” el pago se hizo en efectivo.
    En copia de la factura, mostrada por Rocío, se firmó que el monto fue recibido.

    Después de ocurrido lo anterior, Magaña Álvarez se comprometió,
    al menos en 5 ocasiones, a firmar el convenio 2, acordándolo así en distintas fechas, sin que éste se hubiera

    Por ello, en Libertad de Palabra decidimos suspender la entrega de facturas en la oficina de Magaña Álvarez, en tanto no
    se firmara el convenio que daba sentido al pago de dichas facturas.

    Lejos de cumplir con la firma del convenio 1, se nos informó que el convenio 2 tampoco
    se concretaría, porque se trabajaría igual que en el 2010, por medio de inserciones,
    y que el costo de la plana se vería levemente reducido.

    Sin embargo, tras la edición de la nota “Degrada a mujeres; Enaltece al gobernador”, la publicidad correspondiente a la
    edición Núm. 185, de plano nos fue suspendida sin ningún aviso.

    Con Magaña Álvarez se pretendía aclarar la reducción en el pago del monto de las inserciones, así como concretar ambos convenios, sin que
    haya sido posible verle para exponerle nuestras dudas.

    Lo anterior porque al enviar carta al gobernador, en el que se narran estos hechos,
    Magaña Álvarez ahora ya no nos contesta el teléfono.
