[原文]Heap-based buffer overflow in the BERDecBitString function in Microsoft ASN.1 library (MSASN1.DLL) allows remote attackers to execute arbitrary code via nested constructed bit strings, which leads to a realloc of a non-null pointer and causes the function to overwrite previously freed memory, as demonstrated using a SPNEGO token with a constructed bit string during HTTP authentication, and a different vulnerability than CVE-2003-0818. NOTE: the researcher has claimed that MS:MS04-007 fixes this issue.


[CNNVD]Microsoft ASN.1 library 'BERDecBitString'函数 堆缓冲区溢出漏洞(CNNVD-200506-113)

        Microsoft ASN.1 library (MSASN1.DLL)的BERDecBitString函数存在堆缓冲区溢出漏洞,远程攻击者可使用嵌套结构化位串,导致对一个非空指针重新分配内存(realloc函数),并利用此函数覆盖指针以前指向的内存,从而执行任意代码。比如HTTP验证中使用带有结构化位串的SPNEGO令牌。
