Transbordamento de heap (heap overflow)

Ocorre quando um programa escreve dados além dos limites de um buffer alocado dinamicamente na memória heap, sobrescrevendo dados adjacentes ou metadados do alocador. Isso permite que um atacante corrompa estruturas críticas, execute código arbitrário ou cause travamento da aplicação.

Example

Uma função recebe um tamanho de entrada sem validar e copia para um buffer: `strcpy(heap_buffer, user_input)` sem verificar se user_input cabe. Se o usuário enviar 1000 bytes para um buffer de 256, o overflow sobrescreve estruturas próximas no heap e pode ser explorado para RCE.

How to mitigate

Use funções seguras de cópia (`strncpy`, `strlcpy`), valide e limite o tamanho da entrada antes de copiar, e considere usar linguagens com gerenciamento automático de memória ou ferramentas como AddressSanitizer durante testes para detectar overflows.
