[原文]libxml2, possibly before 2.5.0, does not properly detect recursion during entity expansion, which allows context-dependent attackers to cause a denial of service (memory and CPU consumption) via a crafted XML document containing a large number of nested entity references, aka the "billion laughs attack."

[机译]可能之前2.5.0,libxml2的,不正确地检测到递归过程中实体的扩展,它允许通过一个特制的XML文件,其中包含了大量的嵌套实体引用,也就是依赖于上下文的攻击者造成拒绝服务(内存和CPU的消耗)
