[原文]Unspecified vulnerability in (1) apreq_parse_headers and (2) apreq_parse_urlencoded functions in Apache2::Request (Libapreq2) before 2.07 allows remote attackers to cause a denial of service (CPU consumption) via unknown attack vectors that result in quadratic computational complexity.

[CNNVD]Apache2::Request 未明漏洞(CNNVD-200602-279)

        Apache2::Request (Libapreq2) 2.07之前版本的(1) apreq_parse_headers和(2) apreq_parse_urlencoded功能中存在未明漏洞。远程攻击者可以借助导致二次计算复杂性的未知攻击向量造成拒绝服务(CPU占用率高)。
