Title
libaribb24 through 1.0.3 Stack Buffer Overflow via decoder_handle_csi
Summary
libaribb24 (aribb24) through 1.0.3 contains a stack-based buffer overflow vulnerability in decoder_handle_csi() in src/decoder.c that allows attackers to write past a fixed 256-entry array by supplying unbounded CSI parameter bytes. Attackers can embed a caption statement with a CSI introducer and over 256 parameter bytes in media files or broadcast streams to crash FFmpeg or VLC or corrupt the return address.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.
