CVE-2006-3638

Status: ModifiedHigh (7.5)—

Microsoft Internet Explorer 5.01 and 6 does not properly handle uninitialized COM objects, which allows remote attackers to cause a denial of service (memory corruption) and possibly execute arbitrary code, as demonstrated by the Nth function in the DirectAnimation.DATuple ActiveX control, aka "COM Object Instantiation Memory Corruption Vulnerability."

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
