Foi identificada uma vulnerabilidade no pacote de escrit\u00f3rio livre LibreOffice (CVE-2022-3140) que permite a execu\u00e7\u00e3o de scripts arbitr\u00e1rios ao clicar em um link especialmente preparado no documento ou ao acionar um determinado evento durante o trabalho com o documento. O problema foi corrigido nas atualiza\u00e7\u00f5es do LibreOffice 7.3.6 e 7.4.1. <\/p>\n

A vulnerabilidade \u00e9 causada pela adi\u00e7\u00e3o de suporte a um esquema de chamada de macros 'vnd.libreoffice.command', espec\u00edfico do LibreOffice. Este esquema pode ser utilizado em URIs aplicados para a integra\u00e7\u00e3o do LibreOffice com servidor<\/a> MS SharePoint. Um atacante pode usar tais URIs para criar links que chamam quaisquer macros internas com argumentos arbitr\u00e1rios. Ao clicar ou ativar um evento no documento, esses links podem ser utilizados para executar scripts sem alertar o usu\u00e1rio.
