Subject: [FFmpeg-devel] [PATCH 5/5] avformat/rtpdec_asf: fix leak in ff_wms_parse_sdp_a_line()
Date: Sun, 29 Jun 2025 14:45:26 +0800
Message-ID: <20250629064526.2992143-6-502024330056@smail.nju.edu.cn> (raw)
In-Reply-To: <20250629064526.2992143-1-502024330056@smail.nju.edu.cn>
In ff_wms_parse_sdp_a_line(), it allocates memory in buf, but doesn't
free buf when avformat_alloc_context() failed. Add av_free(buf) before
return to prevent from leak.
