CVE-2023-34415
https://notcve.org/view.php?id=CVE-2023-34415
When choosing a site-isolated process for a document loaded from a data: URL that was the result of a redirect, Firefox would load that document in the same process as the site that issued the redirect. This bypassed the site-isolation protections against Spectre-like attacks on sites that host an "open redirect". Firefox no longer follows HTTP redirects to data: URLs. This vulnerability affects Firefox < 114. • https://bugzilla.mozilla.org/show_bug.cgi?id=1811999 https://security.gentoo.org/glsa/202401-10 https://www.mozilla.org/security/advisories/mfsa2023-20 • CWE-601: URL Redirection to Untrusted Site ('Open Redirect') •
CVE-2023-34414 – Mozilla: Click-jacking certificate exceptions through rendering lag
https://notcve.org/view.php?id=CVE-2023-34414
The error page for sites with invalid TLS certificates was missing the activation-delay Firefox uses to protect prompts and permission dialogs from attacks that exploit human response time delays. If a malicious page elicited user clicks in precise locations immediately before navigating to a site with a certificate error and made the renderer extremely busy at the same time, it could create a gap between when the error page was loaded and when the display actually refreshed. With the right timing the elicited clicks could land in that gap and activate the button that overrides the certificate error for that site. This vulnerability affects Firefox ESR < 102.12, Firefox < 114, and Thunderbird < 102.12. The Mozilla Foundation Security Advisory describes this flaw as: The error page for sites with invalid TLS certificates was missing the activation-delay Firefox uses to protect prompts and permission dialogs from attacks that exploit human response time delays. If a malicious page elicited user clicks in precise locations immediately before navigating to a site with a certificate error and made the renderer extremely busy at the same time, it could create a gap between when the error page was loaded and when the display actually refreshed. • https://bugzilla.mozilla.org/show_bug.cgi?id=1695986 https://security.gentoo.org/glsa/202312-03 https://security.gentoo.org/glsa/202401-10 https://www.mozilla.org/security/advisories/mfsa2023-19 https://www.mozilla.org/security/advisories/mfsa2023-20 https://www.mozilla.org/security/advisories/mfsa2023-21 https://access.redhat.com/security/cve/CVE-2023-34414 https://bugzilla.redhat.com/show_bug.cgi?id=2212841 • CWE-295: Improper Certificate Validation CWE-449: The UI Performs the Wrong Action •
