Use-after-free vulnerability in the Element::normalizeAttributes function in dom/Element.cpp in WebCore in WebKit in Google Chrome before 5.0.375.70 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via vectors related to handlers for DOM mutation events, aka rdar problem 7948784. NOTE: this might overlap CVE-2010-1759.

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).

Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
