## Instruções para a IA do operador
- Confira o ambiente real, o fornecedor, o produto, a plataforma e as versões instaladas no alerta oficial atual e nas informações de lançamento antes de propor uma alteração. Preserve as plataformas, o status padrão e os limites de versões e mudanças de cada entrada de produto; nunca deduza uma correção de um limite de faixa ou de uma entrada não afetada.

- Obtenha aprovação do operador antes de alterações em produção. Nenhum comando ou remediação foi gerado. Este snapshot histórico não comprova aplicabilidade atual, correção lançada ou exploração; nenhuma consulta à rede ou chamada de modelo gerou estas orientações.

Dados de correção desconhecidos; nenhuma versão corrigida é deduzida aqui. Dados ausentes não comprovam ausência de correção.
Exploração desconhecida; este catálogo não avalia exploração.

title: "Cisco Desk Phone 9800 Series, IP Phone 7800 and 8800 Series, and Video Phone 8875 with SIP Software Denial of Service Vulnerability"
summary: "A vulnerability in Cisco Desk Phone 9800 Series, Cisco IP Phone 7800 and 8800 Series, and Cisco Video Phone 8875 that are running Cisco Session Initiation Protocol (SIP) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.\r\n\r\nThis vulnerability is due to improper memory management when an affected device processes HTTP packets. An attacker could exploit this vulnerability by sending a continuous stream of crafted HTTP packets to the device. A successful exploit could allow the attacker to cause the affected device to continuously consume memory, resulting in a DoS condition. A manual reboot of the device is required to recover from this condition.\r\nNote: For this vulnerability to be exploitable, the phone must be registered to Cisco Unified Communications Manager (Unified CM) and have Web Access enabled. Web Access is disabled by default."
