Crash and memory disclosure via unchecked JPEG lengths
Published Jun 15, 2026 · Updated Jun 15, 2026
Out-of-bounds reads in GStreamer gst-plugins-bad before 1.28.4 allow remote attackers to crash applications via crafted JPEG files. In gstjpegparser.c, gst_jpeg_parse() accepts a bitstream segment length larger than the remaining buffer, and the VA JPEG decoder constructs a byte reader over that inflated range. A user must open or process the file through the vulnerable decoder; the resulting read interrupts the application and exposes adjacent process memory.
