CVE-2022-28282

Al utilizar un enlace con <code>rel="localization"</code>, se podría haber activado un use-after-free al destruir un objeto durante la ejecución de JavaScript y luego hacer referencia al objeto a través de un puntero liberado, lo que provocaría un posible bloqueo explotable. Esta vulnerabilidad afecta a Thunderbird &lt; 91.8, Firefox &lt; 99 y Firefox ESR &lt; 91.8.

A flaw was found in Mozilla. The Mozilla Foundation Security Advisory describes this flaw as: By using a link with rel="localization," a use-after-free could have been triggered by destroying an object during JavaScript execution and then referencing the object through a freed pointer, leading to a potentially exploitable crash.

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, conduct spoofing attacks, or execute arbitrary code. It was discovered that Thunderbird ignored OpenPGP revocation when importing a revoked key in some circumstances. An attacker could potentially exploit this by tricking the user into trusting the authenticity of a message or tricking them into use a revoked key to send an encrypted message.
