Microsoft : Security Vulnerabilities, CVEs, Published In May 2005 (Memory corruption)

Heap-based buffer overflow in the SvrAppendReceivedChunk function in xlsasink.dll in the SMTP service of Exchange Server 2000 and 2003 allows remote attackers to execute arbitrary code via a crafted X-LINK2STATE extended verb request to the SMTP port.

Buffer overflow in the URL processor of Microsoft Internet Explorer 5.01, 5.5, and 6 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a URL with a long hostname, aka "URL Parsing Memory Corruption Vulnerability."

Race condition in the memory management routines in the DHTML object processor in Microsoft Internet Explorer 5.01, 5.5, and 6 allows remote attackers to execute arbitrary code via a malicious web page or HTML e-mail, aka "DHTML Object Memory Corruption Vulnerability".

Internet Explorer 5.01, 5.5, and 6 does not properly validate buffers when handling certain DHTML methods including the createControlRange Javascript function, which allows remote attackers to execute arbitrary code, aka the "DHTML Method Heap Memory Corruption Vulnerability."
