Descriptions

Integer overflow in matroskademux element in gst_matroska_demux_add_wvpk_header function which allows a heap overwrite while parsing matroska files. Potential for arbitrary code execution through heap overwrite.

Desbordamiento de enteros en el elemento matroskademux en la función gst_matroska_demux_add_wvpk_header que permite una sobreescritura en el montón mientras se analizan los archivos matroska. Potencial para la ejecución de código arbitrario a través de la sobreescritura de la pila.

A flaw was found in GStreamer. An integer overflow can lead to a heap-based buffer overflow in the mkv demuxer when processing a specially crafted Matroska file. This vulnerability can result in application crash, memory corruption, and code execution.

An update that fixes 7 vulnerabilities is now available. This update for gstreamer-plugins-good fixes the following issues. Fixed integer overflow in WavPack header handling code. Fixed integer overflow resulting in heap corruption in avidemux element. Fixed integer overflows in mkv demuxing. Fixed integer overflows in mkv demuxing using bzip.
