Description
Integer underflow in the CDownloadSink class code in the Vector Markup Language (VML) component (VGX.DLL), as used in Internet Explorer 5.01, 6, and 7 allows remote attackers to execute arbitrary code via compressed content with an invalid buffer size, which triggers a heap-based buffer overflow.
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.
