CVE-2023-7256

In affected libpcap versions during the setup of a remote packet capture the internal function sock_initaddress() calls getaddrinfo() and possibly freeaddrinfo(), but does not clearly indicate to the caller function whether freeaddrinfo() still remains to be called after the function returns. This makes it possible in some scenarios that both the function and its caller call freeaddrinfo() for the same allocated memory block. A similar problem was reported in Apple libpcap, to which Apple assigned CVE-2023-40400.

Summary
  • (es) En las versiones de libpcap afectadas, durante la configuración de una captura de paquetes remota, la función interna sock_initaddress() llama a getaddrinfo() y posiblemente a freeaddrinfo(), pero no indica claramente a la función que la llama si aún queda por llamar a freeaddrinfo() después de que la función regrese. Esto hace posible en algunos escenarios que tanto la función como su llamador llamen a freeaddrinfo() para el mismo bloque de memoria asignado. Se informó un problema similar en Apple libpcap, al que Apple le asignó CVE-2023-40400.
