Descriptions

There is a possible denial of service vulnerability in Action View (Rails) <5.2.2.1, <5.1.6.2, <5.0.7.2, <4.2.11.1 where specially crafted accept headers can cause action view to consume 100% cpu and make the server unresponsive.

Hay una posible vulnerabilidad de denegación de servicio (DoS) en la vista de acción en Rails, en versiones anteriores a las 5.2.2.1, 5.1.6.2, 5.0.7.2 y 4.2.11.1 donde las cabeceras de aceptación especialmente manipuladas pueden provocar que dicha vista consuma el 100 % de la CPU y haga que el servidor deje de responder.

An update that fixes two vulnerabilities is now available. This update for rubygem-actionpack-5_1 fixes the following issues. Fixed a file content disclosure vulnerability in Action View which could be exploited via specially crafted accept headers in combination with calls to render file. Fixed a resource exhaustion issue in Action View which could make the server unable to process requests. This update was imported from the SUSE:SLE-15:Update update project.
