Descriptions

An issue was discovered in Varnish HTTP Cache 4.0.1 through 4.0.4, 4.1.0 through 4.1.7, 5.0.0, and 5.1.0 through 5.1.2. A wrong if statement in the varnishd source code means that particular invalid requests from the client can trigger an assert, related to an Integer Overflow. This causes the varnishd worker process to abort and restart, losing the cached contents in the process. An attacker can therefore crash the varnishd worker process on demand and effectively keep it from serving content - a Denial-of-Service attack. The specific source-code filename containing the incorrect statement varies across releases.

Se ha descubierto un problema en Varnish HTTP Cache 4.0.1 a 4.0.4; 4.1.0 a 4.1.7; 5.0.0; y 5.1.0 a 5.1.2. Una instrucción if incorrecta en el código fuente de varnishd significa que ciertas peticiones no válidas formuladas por el cliente pueden desembocar en una aserción, relacionada con un desbordamiento de enteros. Esto provoca que el proceso de trabajo varnishd se anule y se reinicie, perdiendo todos los contenidos de la caché en el proceso. Por lo tanto, un atacante puede bloquear el proceso de trabajo varnishd cuando quiera y evitar de forma efectiva que envíen contenidos (ataque por Denegación de Servicio). El nombre de archivo de código fuente específico que contiene la instrucción errónea varía según las versiones.
