CVE-2016-1960
HighSummary
An integer underflow in the nsHtml5TreeBuilder class in the HTML5 string parser in Mozilla Firefox before version 45.0 and Firefox ESR 38.x before version 38.7 allows remote attackers to execute arbitrary code or cause a denial of service (use-after-free) by mishandling end tags.
Risk Assessment
This vulnerability can lead to severe consequences, such as remote code execution or service disruption, posing a security threat to systems using the affected versions of the browser.
Recommendation
