The GPS component in Android before 2016-12-05 allows man-in-the-middle attackers to cause a denial of service (GPS signal-acquisition delay) via an incorrect xtra.bin or xtra2.bin file on a spoofed Qualcomm gpsonextra.net or izatcloud.net host, aka internal bug 31470303 and external bug 211602 (and AndroidID-7225554).

Extended Description

Access control involves the use of several protection mechanisms such as:

When any mechanism is not applied or otherwise fails, attackers can compromise the security of the product by gaining privileges, reading sensitive information, executing commands, evading detection, etc. There are two distinct behaviors that can introduce access control weaknesses:

Potential Mitigations

  • Compartmentalize the system to have “safe” areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
  • Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
