CVE-2015-4473

CWE-119Published: August 16, 2015· Updated: Jun 17, 2026

10.0

CVSS v3.1

Official Description

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 40.0 and Firefox ESR 38.x before 38.2 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Technical Analysis

CVE-2015-4473 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-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
