CVE-2025-29364

spimsimulator spim v9.1.24 and before is vulnerable to Buffer Overflow in the READ_SYSCALL and WRITE_SYSCALL system calls. The application verifies the legitimacy of the starting and ending addresses for memory read/write operations. By configuring the starting and ending addresses for memory read/write to point to distinct memory segments within the virtual machine, it is possible to circumvent these checks.

Summary		(es) spimsimulator spim v9.1.24 y anteriores es vulnerable a desbordamiento de búfer en las llamadas al sistema READ_SYSCALL y WRITE_SYSCALL. La aplicación verifica la legitimidad de las direcciones de inicio y fin para operaciones de lectura/escritura de memoria. Al configurar las direcciones de inicio y fin para lectura/escritura de memoria para que apunten a segmentos de memoria distintos dentro de la máquina virtual, es posible eludir estas comprobaciones.
