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, with attack vectors varying based on implementation. The flaw resides in the processing of Huffman tables, stemming from insufficient validation of user-supplied data length before copying it into a fixed-length heap-based buffer. An attacker can exploit this to execute code within the current process.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
