 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.
