Comment: This advisory references vulnerabilities in products which run on

Package        : icecast2
Version        : 2.4.0-1.1+deb8u2
CVE ID         : CVE-2018-18820
Debian Bug     : 912611


A buffer overflow was discovered in the URL-authentication backend of
the icecast2, the popular open source streaming media server. If the
backend is enabled, then any malicious HTTP client can send a request
for specific resource including a crafted header which can overwrite
the server's stack contents, leading to denial of service and
potentially remote code execution.

For Debian 8 "Jessie", this problem has been fixed in version
2.4.0-1.1+deb8u2.

We recommend that you upgrade your icecast2 packages.
