A double-free could have occurred in vpx_codec_enc_init_multi after a failed allocation when initializing the encoder for WebRTC. This could have caused memory corruption and a potentially exploitable crash. This vulnerability affects Thunderbird < 139 and Thunderbird < 128.11.
Weakness
The product calls free() twice on the same memory address.
