CVE-2026-112281 (GCVE-0-2026-112281)

Vulnerability from nvd – Published: 2026-10-19 13:55 – Updated: 2026-10-19 14:20

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.

CVE-2026-112280 (GCVE-0-2026-112280)

Vulnerability from nvd – Published: 2026-10-19 13:55 – Updated: 2026-10-19 16:34

Title

libaribb24 (aribb24) through 1.0.3 Heap Buffer Overflow via parse_data_unit_statement_body

Summary

libaribb24 (aribb24) through 1.0.3 contains a heap-based buffer overflow vulnerability in src/parser.c that allows attackers to corrupt heap memory via an oversized caption data unit. Attackers can supply a crafted caption PES packet in a media file or broadcast stream, processed through arib_parse_pes(), to crash FFmpeg or VLC and possibly corrupt further memory.

Vulnerability from cvelistv5 – Published: 2026-10-19 13:55 – Updated: 2026-10-19 14:20

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.

CVE-2026-112280 (GCVE-0-2026-112280)

Vulnerability from cvelistv5 – Published: 2026-10-19 13:55 – Updated: 2026-10-19 16:34

Title

libaribb24 (aribb24) through 1.0.3 Heap Buffer Overflow via parse_data_unit_statement_body

Summary

libaribb24 (aribb24) through 1.0.3 contains a heap-based buffer overflow vulnerability in src/parser.c that allows attackers to corrupt heap memory via an oversized caption data unit. Attackers can supply a crafted caption PES packet in a media file or broadcast stream, processed through arib_parse_pes(), to crash FFmpeg or VLC and possibly corrupt further memory.
