Package: icecast2 Version: 2.4.4-4+b1 Severity: important Tags: upstream Dear Maintainer,
Icecast2 in Debian is affected by this upstream issue with TLS connections (https://gitlab.xiph.org/xiph/icecast-server/-/issues/2355): > When in a TLS SOURCE connection the socket is closed without TLS > teardown Icecast will read from the socket in a tight endless loop. > This locks up the corresponding thread. This has been visibly patched in upstream's VCS, in a 2.4.5 branch that looks like it has not been released yet: https://gitlab.xiph.org/xiph/icecast-server/-/commit/8662884447efc414e885b20b965f465d37a01fb5 I applied this patch by simply dowloading the txt version from GitLab: https://gitlab.xiph.org/xiph/icecast-server/-/commit/8662884447efc414e885b20b965f465d37a01fb5.patch I am currently running a patched version of icecast2 and the problems seems to be fixed. A reliable way to reproduce the issue is to enable TLS, create a stream with BUTT and have at least one listener (e.g. with firefox), then click the stop button of BUTT. This make icecast use 100% of a CPU while beeing in a waiting state. The bug did not happen back yet with the patched version. Could you please add this patch to the patch series? -- Nicolas Peugnet
