AI Insight

LLM-synthesized narrative grounded in this CVE's description and references.

Integer overflow in GStreamer's matroskademux element leads to heap overwrite, potentially allowing arbitrary code execution via crafted Matroska files.

Vulnerability

Integer overflow in the gst_matroska_demux_add_wvpk_header function of the matroskademux element in GStreamer allows a heap overwrite while parsing Matroska files. The vulnerability exists in versions prior to the fix.

Exploitation

An attacker can exploit this by providing a specially crafted Matroska file that triggers the integer overflow during parsing. No authentication is required; the victim only needs to open the malicious file with a GStreamer-based application.

Impact

Successful exploitation allows an attacker to overwrite heap memory, potentially leading to arbitrary code execution with the privileges of the application using GStreamer.

Mitigation

The vulnerability was fixed in a later GStreamer release. Users should update to the latest version. No workaround is disclosed in the available references.
