Os desenvolvedores do PHP publicaram um relat\u00f3rio sobre os problemas que surgiram durante o processo de corre\u00e7\u00e3o das vulnerabilidades cr\u00edticas corrigidas ontem no PHP. A informa\u00e7\u00e3o sobre a vulnerabilidade que ocorre devido ao esgotamento da mem\u00f3ria dispon\u00edvel foi obtida durante uma auditoria externa no ano de 2024, mas foi considerada apenas como uma possibilidade te\u00f3rica de ataque. A corre\u00e7\u00e3o se atrasou devido a problemas para alcan\u00e7ar um consenso entre os desenvolvedores do PHP sobre a forma de resolver a vulnerabilidade. V\u00e1rias propostas concorrentes para resolver o problema foram consideradas, cada uma com suas desvantagens. Era necess\u00e1rio escolher entre violar a compatibilidade retroativa, criar novos vetores para ataques que causariam nega\u00e7\u00e3o de servi\u00e7o, e a necessidade de modificar uma infinidade de complementos de terceiros. <\/p>\n

H\u00e1 alguns meses, as empresas Calif e Wiz, de forma independente, utilizaram modelos de IA GPT-5.6 e Gemini 4 Argon para identificar m\u00e9todos eficazes de explora\u00e7\u00e3o do problema e informaram os desenvolvedores do PHP sobre isso nos dias 11 e 24 de agosto de 2026. Ap\u00f3s isso, o desenvolvimento de corre\u00e7\u00f5es foi atribu\u00eddo \u00e0 mais alta prioridade e o processo de tomada de decis\u00e3o come\u00e7ou a ser reformulado para uma resposta mais \u00e1gil em quest\u00f5es relacionadas a compromissos complexos (decis\u00f5es desse tipo agora podem ser tomadas pela maioria dos votos, sem a necessidade de alcan\u00e7ar consenso rigoroso).<\/p>\n

Inicialmente, a data de publica\u00e7\u00e3o da corre\u00e7\u00e3o coordenada com as distribui\u00e7\u00f5es foi marcada para 22 de outubro, mas foi adiantada para 21 de outubro ap\u00f3s o vazamento, em 20 de outubro, nas redes sociais de informa\u00e7\u00f5es sobre os identificadores CVE e dados incorretos sobre o hor\u00e1rio de publica\u00e7\u00e3o das pr\u00f3ximas vers\u00f5es corretivas. <\/p>\n

Logo ap\u00f3s o an\u00fancio das pr\u00f3ximas corre\u00e7\u00f5es, a empresa Calif, que identificou uma das vulnerabilidades, acidentalmente publicou um v\u00eddeo demonstrando o funcionamento do exploit, no qual eram vis\u00edveis alguns detalhes que possibilitavam restringir a busca e a recria\u00e7\u00e3o de informa\u00e7\u00f5es sobre o problema. O v\u00eddeo foi rapidamente removido, o que apenas incentivou os pesquisadores a se aprofundarem na vulnerabilidade e acelerou o trabalho em prot\u00f3tipos alternativos de exploits. <\/p>\n

Al\u00e9m disso, seis horas antes da publica\u00e7\u00e3o programada das corre\u00e7\u00f5es, a empresa Chainguard quebrou o embargo e publicou compila\u00e7\u00f5es de sua distribui\u00e7\u00e3o contendo a vers\u00e3o corrigida do PHP. Essa viola\u00e7\u00e3o permitiu que os criminosos analisassem a corre\u00e7\u00e3o antes do lan\u00e7amento oficial, al\u00e9m de comprometer todo o trabalho de divulga\u00e7\u00e3o coordenada e da publica\u00e7\u00e3o simult\u00e2nea das corre\u00e7\u00f5es em diferentes distribui\u00e7\u00f5es.<\/p>\n

Adicionalmente: Ap\u00f3s 16 horas da divulga\u00e7\u00e3o dos detalhes sobre as vulnerabilidades do exploit universal, n\u00e3o houve ataques em massa at\u00e9 o momento, o que pode ser explicado pela complexidade de explora\u00e7\u00e3o da vulnerabilidade devido \u00e0 necessidade de determinar o layout das estruturas na mem\u00f3ria do processo, que \u00e9 espec\u00edfica para cada compila\u00e7\u00e3o. Os prot\u00f3tipos de exploits publicados est\u00e3o atrelados a configura\u00e7\u00f5es espec\u00edficas e \u00e0 realiza\u00e7\u00e3o de ataques em condi\u00e7\u00f5es laboratoriais. Tamb\u00e9m surgiram muitos exploits fict\u00edcios, que s\u00e3o alucina\u00e7\u00f5es de IA, criando apenas a ilus\u00e3o de ataques, relacionados a erros de configura\u00e7\u00e3o ou que funcionam apenas na presen\u00e7a de outras vulnerabilidades cr\u00edticas.
