Subject: [FFmpeg-devel] [PATCH] avformat/rtmpproto: fix rmtp packet leak in gen_connect()
Date: Sat, 14 Jun 2025 16:33:50 +0800
Message-ID: <20250614083350.325419-1-502024330056@smail.nju.edu.cn> (raw)
In libavformat/rtmpproto.c:gen_connect(), if check on string length
or check on codec fourcc failed, ff_rtmp_packet_create() allocated
data in pkt would leak. Add ff_rtmp_packet_destory before return error
code.
