Descriptions

The <code>ms-msdt</code>, <code>search</code>, and <code>search-ms</code> protocols deliver content to Microsoft applications, bypassing the browser, when a user accepts a prompt. These applications have had known vulnerabilities, exploited in the wild (although we know of none exploited through Thunderbird), so in this release Thunderbird has blocked these protocols from prompting the user to open them.<br>*This bug only affects Thunderbird on Windows. Other operating systems are unaffected.*. This vulnerability affects Firefox < 102, Firefox ESR < 91.11, Thunderbird < 102, and Thunderbird < 91.11.

Los protocolos <code>ms-msdt</code>, <code>search</code> y <code>search-ms</code> entregan contenido a las aplicaciones de Microsoft, sin pasar por el navegador, cuando un usuario acepta un mensaje. Estas aplicaciones han tenido vulnerabilidades conocidas, explotadas en la naturaleza (aunque sabemos de ninguna explotada a través de Thunderbird), por lo que en esta versión Thunderbird ha bloqueado estos protocolos para que no soliciten al usuario que los abra.<br>*Este error solo afecta a Thunderbird en Windows. Otros sistemas operativos no se ven afectados.*. Esta vulnerabilidad afecta a Firefox < 102, Firefox ESR < 91.11, Thunderbird < 102 y Thunderbird < 91.11.
