CVE-2011-4461 – jetty: hash table collisions CPU usage DoS (oCERT-2011-003)

https://notcve.org/view.php?id=CVE-2011-4461

Jetty 8.1.0.RC2 and earlier computes hash values for form parameters without restricting the ability to trigger hash collisions predictably, which allows remote attackers to cause a denial of service (CPU consumption) by sending many crafted parameters. Jetty v8.1.0.RC2 y anteriores calcula los valores hash de los parámetros de forma, sin restringir la capacidad de desencadenar colisiones hash predecible, lo que permite a atacantes remotos provocar una denegación de servicio (consumo de CPU) mediante el envío de gran cantidad de parámetros a mano. • http://archives.neohapsis.com/archives/bugtraq/2011-12/0181.html http://marc.info/?l=bugtraq&m=143387688830075&w=2 http://secunia.com/advisories/47408 http://secunia.com/advisories/48981 http://www.kb.cert.org/vuls/id/903934 http://www.nruns.com/_downloads/advisory28122011.pdf http://www.ocert.org/advisories/ocert-2011-003.html http://www.oracle.com/technetwork/security-advisory/cpuapr2016v3-2985753.html http://www.oracle.com/technetwork/security-advisory/cpujul2018-4258247.html http • CWE-310: Cryptographic Issues •
