The length of the buffer is controlled by an attacker. By providing a length smaller than 0xCC, memcpy reaches out of the malloc'ed bound. This possibly leads to memory layout information leaking in the data. This might be used in a chain of vulnerability in order to reach code execution."},{"lang":"es","value":"Se encontró un fallo en dmg2img versiones hasta 20170502.
