Security Fix(es): Assuming a controlled failed memory allocation, an attacker could have caused a use-after-free, leading to a potentially exploitable crash. This vulnerability affects Firefox &lt; 134, Firefox ESR &lt; 128.6, and Firefox ESR &lt; 115.19.(CVE-2025-0238) When using Alt-Svc, ALPN did not properly validate certificates when the original server is redirecting to an insecure site.
