GStreamer is denial of service (DoS). Multiple integer overflow flaws, that could lead to a buffer overflow, were found in the GStreamer Good Plug-ins PNG decoding handler. An attacker could create a specially-crafted PNG file that would cause an application using the GStreamer Good Plug-ins library to crash or, potentially, execute arbitrary code as the user running the application when parsed.
