Streamripper is a tool for extracting and recording mp3 files from a Shoutcast stream.
Chris Rohlf discovered several boundary errors in the httplib_parse_sc_header() function when processing HTTP headers.
A remote attacker could entice a user to connect to a malicious streaming server, resulting in the execution of arbitrary code with the privileges of the user running Streamripper.
There is no known workaround at this time.
All Streamripper users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-sound/streamripper-1.62.2"
