CVE-2023-25746

The Mozilla Foundation Security Advisory describes this flaw as: Mozilla developers Philipp and Gabriele Svelto reported memory safety bugs present in Firefox ESR 102.7. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code.

Multiple security issues were discovered in Thunderbird. If a user were tricked into opening a specially crafted website in a browsing context, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information, bypass security restrictions, cross-site tracing, or execute arbitrary code. Johan Carlsson discovered that Thunderbird did not properly implement CSP policy on a header when using iframes. An attacker could potentially exploits this to exfiltrate data.
