CVE-2017-13179 Information

Description

In the ihevcd_allocate_static_bufs and ihevcd_create functions of SoftHEVC there is a possible out-of-bounds write due to a use after free. Both ps_codec_obj and ps_create_op-s_ivd_create_op_t.pv_handle point to the same memory and ps_codec_obj could be freed without clearing ps_create_op-s_ivd_create_op_t.pv_handle. This could lead to remote code execution as a privileged process with no additional execution privileges needed. User interaction is not needed for exploitation. Product: Android. Versions: 6.0.1 7.0 7.1.1 7.1.2 8.0 8.1. Android ID: A-66969193.
