Name of the Vulnerable Software and Affected Versions GStreamer (affected versions not specified)

Description This issue allows remote attackers to execute arbitrary code on affected installations of GStreamer. Interaction with the library is required for exploitation, and attack vectors may vary. The flaw resides within the parsing of decoding units, stemming from insufficient validation of user-supplied data length before copying it into a fixed-length stack-based buffer. An attacker can exploit this to execute code within the current process.
