CVE-2014-1478

CWE-787Published: February 6, 2014· Updated: Jun 17, 2026

10.0

CVSS v3.1

Official Description

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 27.0 and SeaMonkey before 2.24 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via vectors related to the MPostWriteBarrier class in js/src/jit/MIR.h and stack alignment in js/src/jit/AsmJS.cpp in OdinMonkey, and unknown other vectors.

Technical Analysis

CVE-2014-1478 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.
