Summary

Race condition in the msxml3 module in Microsoft XML Core Services 3.0, as used in Internet Explorer 6 and other applications, allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via many nested tags in an XML document in an IFRAME, when synchronous document rendering is frequently disrupted with asynchronous events, as demonstrated using a JavaScript timer, which can trigger NULL pointer dereferences or memory corruption, aka "MSXML Memory Corruption Vulnerability."

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
