Reino: Code Quality
Códigos de baixa qualidade levam a comportamentos imprevisíveis. Da perspectiva do usuário, isso normalmente se manifesta como usabilidade ruim. Para um invasor, trata-se de uma oportunidade para atacar o sistema de formas imprevistas.
Unreleased Resource: Synchronization
Abstract
O programa não consegue liberar um bloqueio que ele mantém, o que pode levar a um deadlock.
Explanation
O programa talvez não consiga liberar um recurso do sistema.
Vazamento de recursos têm pelo menos duas causas comuns:
- Condições de erro e outras circunstâncias excepcionais.
- Confusão acerca de qual parte do programa é responsável pela liberação do recurso.
A maioria dos problemas de recursos não liberados resulta em problemas gerais de confiabilidade de software. No entanto, se um invasor puder provocar intencionalmente um vazamento de recursos, talvez ele consiga lançar uma negação de serviço esgotando o pool de recursos.
Exemplo 1: O código a seguir estabelece um bloqueio antes de

Exemplo 1: O código a seguir estabelece um bloqueio antes de
performOperationInCriticalSection()
, mas não consegue liberá-lo quando uma exceção é lançada nesse método.
Object synchronizationObject = new Object ();
System.Threading.Monitor.Enter(synchronizationObject);
performOperationInCriticalSection();
System.Threading.Monitor.Exit(synchronizationObject);

Abstract
O programa não consegue liberar um bloqueio que mantém, o que pode levar a um deadlock.
Explanation
Os vazamentos de recursos têm pelo menos duas causas comuns:
- Condições de erro e outras circunstâncias excepcionais.
- Confusão acerca de qual parte do programa é responsável pela liberação do recurso.
A maioria dos problemas de recursos não liberados resulta em problemas gerais de confiabilidade de software. No entanto, se um invasor puder provocar intencionalmente um vazamento de recursos, talvez ele inicie uma negação de serviço esgotando o pool de recursos.
Exemplo 1: O código a seguir estabelece um bloqueio antes de

Exemplo 1: O código a seguir estabelece um bloqueio antes de
performOperationInCriticalSection()
, mas nunca o libera.
let lock1 = OSAllocatedUnfairLock()
lock1.lock()
performOperationInCriticalSection();
