Use After Free

CVE-2017-13179

High
9.8/10

Summary

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.

CWE-416 - Use After Free

Use-after-free (UaF) vulnerability occurs when the application is using a pointer to memory that has been freed. Any attempt to read/write to a buffer after it is de-allocated allows memory corruption, sensitive information exposure, and can potentially lead to arbitrary code execution.
