CVE-2016-1974

HIGH

Firefox < 44.0.2 - Remote Code Execution via Unicode Data in HTML/XML/SVG

Title source: llm

Description

The nsScannerString::AppendUnicodeTo function in Mozilla Firefox before 45.0 and Firefox ESR 38.x before 38.7 does not verify that memory allocation succeeds, which allows remote attackers to execute arbitrary code or cause a denial of service (out-of-bounds read) via crafted Unicode data in an HTML, XML, or SVG document.
