The nsImageGeometryMixin class in Mozilla Firefox before 49.0, Firefox ESR 45.x before 45.4, and Thunderbird < 45.4 does not properly perform a cast of an unspecified variable during handling of INPUT elements, which allows remote attackers to execute arbitrary code via a crafted web site.
CVE-2016-5271 1 Mozilla 1 Firefox 2026-06-17 4.3 MEDIUM 6.5 MEDIUM
The PropertyProvider::GetSpacingInternal function in Mozilla Firefox before 49.0 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via text runs in conjunction with a "display: contents" Cascading Style Sheets (CSS) property.
CVE-2016-5270 1 Mozilla 1 Firefox 2026-06-17 7.5 HIGH 9.8 CRITICAL
Heap-based buffer overflow in the nsCaseTransformTextRunFactory::TransformString function in Mozilla Firefox before 49.0, Firefox ESR 45.x before 45.4, and Thunderbird < 45.4 allows remote attackers to cause a denial of service (boolean out-of-bounds write) or possibly have unspecified other impact via Unicode characters that are mishandled during text conversion.
CVE-2016-5268 1 Mozilla 1 Firefox 2026-06-17 4.3 MEDIUM 4.3 MEDIUM
Mozilla Firefox before 48.0 does not properly set the LINKABLE and URI_SAFE_FOR_UNTRUSTED_CONTENT flags of about: URLs that are used for error pages, which makes it easier for remote attackers to conduct spoofing attacks via a crafted URL, as demonstrated by misleading text after an about:neterror?d= substring.
CVE-2016-5267 2 Google, Mozilla 2 Android, Firefox 2026-06-17 4.3 MEDIUM 5.3 MEDIUM

The nsDisplayList::HitTest function in Mozilla Firefox before 48.0 and Firefox ESR 45.x before 45.3 mishandles rendering display transformation, which allows remote attackers to execute arbitrary code via a crafted web site that leverages "type confusion."
CVE-2016-5262 2 Mozilla, Oracle 2 Firefox, Linux 2026-06-17 4.3 MEDIUM 6.1 MEDIUM
Mozilla Firefox before 48.0 and Firefox ESR 45.x before 45.3 process JavaScript event-handler attributes of a MARQUEE element within a sandboxed IFRAME element that lacks the sandbox="allow-scripts" attribute value, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via a crafted web site.
