**Nome do Software Vulnerável e Versões Afetadas** Thunderbird versão 150 Firefox versão 150 **Descrição** Falhas de segurança de memória envolvendo corrupção de memória podem permitir que um invasor execute código arbitrário. **Recomendações** Atualize o Thunderbird para a versão 151. Atualize o Firefox para a versão 151.

**Nome do software vulnerável e versões afetadas** Versões do Firefox anteriores à 126 Versões do Firefox para Android anteriores à 126 **Descrição** O problema decorre do uso de um hash MD5 inseguro para armazenar manifestos de aplicativos web, permitindo uma colisão de hash que poderia sobrescrever o manifesto de outro aplicativo. Isso poderia ser explorado para executar código arbitrário no contexto de outro aplicativo. **Recomendações** Para versões do Firefox anteriores à 126, atualize para a versão 126 ou posterior para resolver o problema. Para versões do Firefox para Android anteriores à 126, atualize para a versão 126 ou posterior para resolver o problema.

**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 63 **Description** The issue is caused by memory safety bugs, including evidence of memory corruption, which could potentially be exploited to run arbitrary code. This is due to a buffer overflow in memory, allowing a remote attacker to execute arbitrary code. **Recommendations** For versions prior to 63, update to version 63 or later to resolve the issue. As a temporary workaround, consider restricting access to sensitive resources until the update is applied.

**Name of the Vulnerable Software and Affected Versions** Mozilla Network Security Services (NSS) versions prior to 3.19.2.1 Mozilla Network Security Services (NSS) versions 3.20.x prior to 3.20.1 Firefox versions prior to 42.0 Firefox ESR 38.x versions prior to 38.4 **Description** The issue is caused by a heap-based buffer overflow in the ASN.1 decoder. This can be exploited by remote attackers using specially crafted OCTET STRING data, potentially leading to a denial of service or the execution of arbitrary code. **Recommendations** For Mozilla Network Security Services (NSS) versions prior to 3.19.2.1, update to version 3.19.2.1 or later. For Mozilla Network Security Services (NSS) versions 3.20.x prior to 3.20.1, update to version 3.20.1 or later. For Firefox versions prior to 42.0, update to version 42.0 or later. For Firefox ESR 38.x versions prior to 38.4, update to version 38.4 or later.

**Name of the Vulnerable Software and Affected Versions** Mozilla Firefox versions prior to 39.0 Firefox ESR versions prior to 38.1 Thunderbird versions prior to 38.1 **Description** The issue allows user-assisted man-in-the-middle attackers to bypass intended access restrictions. This can be achieved by triggering a user dialog for an X.509 certificate problem, such as an expired certificate or a mismatched hostname for a domain with pinning enabled. **Recommendations** For Mozilla Firefox versions prior to 39.0, update to version 39.0 or later to resolve the issue. For Firefox ESR versions prior to 38.1, update to version 38.1 or later to resolve the issue. For Thunderbird versions prior to 38.1, update to version 38.1 or later to resolve the issue.

**Name of the Vulnerable Software and Affected Versions** Mozilla Firefox versions 3.0.x through 3.0.14 Mozilla Firefox versions 3.5.x through 3.5.3 **Description** The issue affects the browser engine, allowing remote attackers to cause a denial of service, which results in memory corruption and application crash, or possibly execute arbitrary code via unknown vectors. **Recommendations** For Mozilla Firefox versions 3.0.x through 3.0.14, update to version 3.0.15 or later. For Mozilla Firefox versions 3.5.x through 3.5.3, update to version 3.5.4 or later.
