**Nome do software vulnerável e versões afetadas** Versões do macOS Catalina anteriores à 10.15.3 **Descrição** Um problema de corrupção de memória foi corrigido com um gerenciamento de memória aprimorado, o que permitia que um aplicativo pudesse executar código arbitrário com privilégios de sistema. **Recomendações** Para versões do macOS Catalina anteriores à 10.15.3, atualize para o macOS Catalina 10.15.3 para resolver o problema.

**Name of the Vulnerable Software and Affected Versions** macOS versions prior to 10.13.5 **Description** The issue involves the "Grand Central Dispatch" component and allows attackers to bypass a sandbox protection mechanism. This is achieved by leveraging the misparsing of entitlement plists, which can occur during the authorization process. The exploitation of this issue may enable an attacker to circumvent the restrictions of an isolated environment. **Recommendations** For macOS versions prior to 10.13.5, update to version 10.13.5 or later to resolve the issue. As a temporary workaround, consider restricting access to the "Grand Central Dispatch" component until a patch is applied.
