CVE-2009-2466

CWE-787Published: July 22, 2009· Updated: Jun 16, 2026

10.0

CVSS v3.1

Official Description

The JavaScript engine in Mozilla Firefox before 3.0.12 and Thunderbird allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via vectors related to (1) nsDOMClassInfo.cpp, (2) JS_HashTableRawLookup, and (3) MirrorWrappedNativeParent and js_LockGCThingRT.

Technical Analysis

CVE-2009-2466 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

From a weakness classification perspective (CWE-787): Out-of-bounds write vulnerabilities can lead to data corruption, crashes, or arbitrary code execution.
