NVD Description

Note: Versions mentioned in the description apply only to the upstream ffmpeg-8.1-libswscale9 package and not the ffmpeg-8.1-libswscale9 package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

FFmpeg before 8.1.3 and 9.x before 9.0.2 contains an improper certificate validation vulnerability in tls_open() of libavformat/tls_mbedtls.c, which skips hostname checks for IP-address hosts. Network attackers can intercept https, rtmps, or tls connections to IP-literal URLs with any trusted CA-issued certificate to read and tamper with streams.
