CVE-2022-1097

Se hacía referencia a los objetos <code>NSSToken</code> a través de puntos directos y se podría haber accedido a ellos de forma insegura en diferentes subprocesos, lo que provocó un use after free y un bloqueo potencialmente 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 the issue of NSSToken objects referenced via direct points that could have been accessed unsafely on different threads, leading to a use-after-free and 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.
