Summary
firefox vulnerabilities
Details

Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information across domains, or execute arbitrary code. (CVE-2025-0237, CVE-2025-0239, CVE-2025-0240, CVE-2025-0242, CVE-2025-0243, CVE-2025-0247)

Irvan Kurniawan discovered that Firefox incorrectly handled memory when breaking lines in text, leading to a use-after-free vulnerability. An attacker could possibly use this issue to cause a denial of service or possibly execute arbitrary code. (CVE-2025-0238)

Nils Bars discovered that Firefox incorrectly handled memory when using JavaScript Text Segmentation. An attacker could possibly use this issue to cause a denial of service. (CVE-2025-0241)
