GStreamer Base Plugins: Heap-based buffer overflow

Background

A well-groomed and well-maintained collection of GStreamer plug-ins and elements, spanning the range of possible types of elements one would want to write for GStreamer.

Description

It was discovered that GStreamer Base Plugins did not correctly handle certain malformed RTSP streams.

Impact

A remote attacker could entice a user to open a specially crafted RTSP stream with a GStreamer application, possibly resulting in the execution of arbitrary code or a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All GStreamer Base Plugins users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose
 ">=media-libs/gst-plugins-base-1.14.5-r1"
