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-2025-1011, CVE-2025-1013, CVE-2025-1014, CVE-2025-1016, CVE-2025-1017, CVE-2025-1018, CVE-2025-1019, CVE-2025-1020)

Ivan Fratric discovered that Firefox did not properly handle XSLT data, leading to a use-after-free vulnerability. An attacker could potentially exploit this issue to cause a denial of service, or execute arbitrary code. (CVE-2025-1009)

Atte Kettunen discovered that Firefox did not properly manage memory in the Custom Highlight API, leading to a use-after-free vulnerability. An attacker could potentially exploit this issue to cause a denial of service, or execute arbitrary code. (CVE-2025-1010)

Nils Bars discovered that Firefox did not properly manage memory during concurrent delazification, leading to a use-after-free vulnerability. An attacker could potentially exploit this issue to cause a denial of service, or execute arbitrary code. (CVE-2025-1012)
