Description
Buffer overflow in the HTML Converter (HTML32.cnv) on various Windows operating systems allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via cut-and-paste operation, as demonstrated in Internet Explorer 5.0 using a long "align" argument in an HR tag.
Public exploits
Exploit or proof-of-concept code for this vulnerability is publicly available, which lowers the bar for attackers. Treat it as a reason to patch sooner.
Third-party code, not reviewed by us. Public PoCs are sometimes fake or contain malware. Read the code first and run it only in an isolated lab, against systems you are authorised to test.
