CVSS: 5.0EPSS: 0%CPEs: 9EXPL: 0CVE-2012-5371 – ruby: Murmur hash-flooding DoS flaw in ruby 1.9 (oCERT-2012-001)
https://notcve.org/view.php?id=CVE-2012-5371
Ruby (aka CRuby) 1.9 before 1.9.3-p327 and 2.0 before r37575 computes hash values without properly restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted input to an application that maintains a hash table, as demonstrated by a universal multicollision attack against a variant of the MurmurHash2 algorithm, a different vulnerability than CVE-2011-4815. Ruby (también conocido como CRuby) v1.9 anteriores a v1.9.3-p327 y v2.0 anteriores a r37575 calcula los valores de hash sin restringir la posibilidad de provocar colisiones hash previsibles, lo que permite a atacantes dependientes de contexto provocar una denegación de servicio (consumo de CPU) a través de la manipulación de una entrada para la aplicación que mantiene la tabla de valores hash, como lo demuestra un ataque universal multicolision contra una variante del algoritmo MurmurHash2, una vulnerabilidad diferente a CVE-2011-4815. • http://2012.appsec-forum.ch/conferences/#c17 http://asfws12.files.wordpress.com/2012/11/asfws2012-jean_philippe_aumasson-martin_bosslet-hash_flooding_dos_reloaded.pdf http://secunia.com/advisories/51253 http://securitytracker.com/id?1027747 http://www.ocert.org/advisories/ocert-2012-001.html http://www.osvdb.org/87280 http://www.ruby-lang.org/en/news/2012/11/09/ruby19-hashdos-cve-2012-5371 http://www.securityfocus.com/bid/56484 http://www.ubuntu.com/usn/USN-1733-1 http • CWE-310: Cryptographic Issues •
