[原文]Heap-based buffer overflow in URLMON.DLL in Microsoft Internet Explorer 6 SP1 on Windows 2000 and XP SP1, with versions the MS06-042 patch before 20060912, allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a long URL in a GZIP-encoded website that was the target of an HTTP redirect, due to an incomplete fix for CVE-2006-3869.


[CNNVD]Microsoft IE压缩内容URL堆溢出漏洞(CNNVD-200609-164)

        Internet Explorer是微软发布的非常流行的WEB浏览器。
        IE新发布的补丁中出现了一个处理URL的堆溢出漏洞,远程攻击者可能利用此漏洞在用户机器上执行任意指令。
        由于没有正确的使用lstrcpynA,带有MS06-042补丁的URLMON.DLL中存在堆溢出漏洞。CMimeFt::Create为CMimeFt类的新例程分配了390h字节的堆块,其中的+160h偏移处存在104h (MAX_PATH)字节的ASCII字符缓冲区:
        1A4267F8 push 390h ; cb
        1A4267FD call ??2@YAPAXI@Z ; operator new(uint)
        如果访问URL能够导致HTTP重新定向(300到303状态),且之后访问"Location"字段返回GZIP或deflate编码的参数数据,CMimeFt::ReportProgress就会试图使用lstrcpynA API函数将URL拷贝到104h字节的字符串缓冲区,但最多传递了824h(10进制为2084)的长度参数,这是URL通常可使用的最大长度:
        1A425D41 push 824h ; iMaxLength
        1A425D46 push eax ; lpString2
        1A425D47 add esi, 15Ch
        1A425D4C push esi ; lpString1
        1A425D4D call ds:lstrcpynA
        这样攻击者就可以使用恶意URL中的数据覆盖CMimeFt类例程及相邻堆块中的内容。

30834
Microsoft IE URLMON.DLL Long URL HTTP Redirect Overflow
Remote / Network Access Input Manipulation
Loss of Integrity
Vendor Verified

- 漏洞描述

A remote buffer overflow exists in URLMON.DLL of Microsoft Internet Explorer. The browser fails to check the bounds on long URLs when using the HTTP 1.1 protocol and GZip compression resulting in a heap-based buffer overflow. With a specially crafted request, an attacker can cause execution of arbitrary code resulting in a loss of integrity.

- 漏洞讨论

Microsoft Internet Explorer is prone to a remote buffer-overflow vulnerability. A successful exploit may result in arbitrary code-execution in the context of the user running the browser.

This issue was introduced with the rereleased patches of Microsoft advisory MS06-042.

This issue is nearly identical to that discussed in BID 19667 (Microsoft Internet Explorer HTTP 1.1 and Compression Long URI Buffer Overflow Vulnerability), but is a separate vulnerability.
