漏洞描述
中文描述:

Apache是一款开放源代码流行的Web服务程序。Apache ap_escape_html内存分配存在问题，远程攻击者可以利用这个漏洞对Apache服务程序进行拒绝服务攻击。问题存在于server/protocol.c ap_get_mime_headers_core:------ if (last_field != NULL) { if ((len > 0) && ((*field == ' ') || *field == ' ')) {...fold_buf = (char *)apr_palloc(r->pool， alloc_len);-----如果头字段以TAB或SPACE开始，Apache就会分配内存给它。而在ap_escape_html(r->pool， last_field)函数中，last_field字段可以任意长，根据如下代码：----int i， j;for (i = 0， j = 0; s[i] != ''; i++) if (s[i] == '<' || s[i] == '>') j += 3; else if (s[i] == '&') j += 4; if (j == 0) return apr_pstrmemdup(p， s， i); x = apr_palloc(p， i + j + 1);----(i + j + 1)也可以是任意长度，导致分配任意内存，可消耗大量资源。在linux x86_64上证实发送820MB数据可以溢出(i+j+1)，导致memcpy崩溃而引起拒绝服务。

英文描述:

The ap_get_mime_headers_core function in Apache httpd 2.0.49 allows remote attackers to cause a denial of service (memory exhaustion), and possibly an integer signedness error leading to a heap-based buffer overflow on 64 bit systems, via long header lines with large numbers of space or tab characters.
