I spotted a vulnerability in Icecast, the open source streaming media server maintained by the Xiph.org Foundation. Attackers could craft HTTP headers that would overwrite the server’s stack contents, leading to remote code execution. Since Icecast is commonly used to host internet radio stations, a motivated attacker could potentially take a station off air.https://lgtm.com/blog/icecast_snprintf_CVE-2018-18820
