Package        : rtpengine
Version        : 10.5.3.5-1+deb12u1
CVE ID         : CVE-2025-53399
Debian Bug     : 1110316

It was discovered that there was a origin-validation error in
rtpengine, an open-source media proxy for real-time audio and video
traffic.

CVE-2025-53399

    The endpoint-learning logic of the media-relay core could have
    allowed an remote attacker to inject or intercept media streams
    via malicious RTP packets.

For Debian 12 bookworm, this problem has been fixed in version
10.5.3.5-1+deb12u1.

We recommend that you upgrade your rtpengine packages.
