Description Murray McAllister 2014-11-19 23:25:48 UTC

It was reported that Icecast could possibly leak the contents of on-connect scripts, which may contain sensitive information. This issue has been fixed in the 2.4.1 release:

"Fix on-connect and on-disconnect script STDIN/STDOUT/STDERR corruption due to shared file descriptors."

This should be "on-connect scripts to clients".

Comment 4 Thomas Rücker 2014-11-20 10:54:24 UTC

If this wasn't obvious:
A default installation of Icecast is not affected.
It only becomes a problem if an Icecast server < 2.4.1 has a mountpoint configured with either the on-connect or on-disconnect option.

As upstream I'd personally prefer to see things updated to 2.4.1 (also due to other bugs, including security issues, we fixed and being backwards compatible), but if you only want to address this issue, then cherry picking commits should work fine.
