libstb.so is vulnerable to Double Free. The vulnerability is due to start_decoder function in stb_vorbis.c file does not initialize the memory allocated for f->comment_list. This allows an attacker to craft a file that triggers an early return in the function, leading to setup_free being called on these uninitialized pointers, which could result in memory corruption or code execution.
