Vulnerability Title
N/A
Source: NVD (National Vulnerability Database)
Vulnerability Description
JRuby 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 the MurmurHash2 algorithm, a different vulnerability than CVE-2011-4838.

JRuby ‘MurmurHash2’算法哈希冲突拒绝服务漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
JRuby是面向Ruby、基于Java虚拟机(JVM)的一种解释程序。 JRuby中存在拒绝服务漏洞，该漏洞源于使用哈希函数基于‘MurmurHash2’算法，可预测哈希值冲突。攻击者利用该漏洞发送特制的字符串传送到受影响应用程序，使用这些字符串创建Hash对象（类似HTTP请求）。成功的利用可触发高CPU消耗，导致拒绝访问状态。
