Detailed vulnerability description

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

In get_element_attr_rsp of btif_rc.cc, there is a possible out of bounds write due to a missing bounds check. This could lead to remote code execution if bluetoothtbd were used, which it isn't in typical Android platforms, with no additional execution privileges needed.
