CVE-2005-1935 Information

Description

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.
