libheif is a HEIF and AVIF file format decoder and encoder. In versions 1.21.2 and below, a crafted 800-byte HEIF sequence file causes an infinite loop in Box_stts::get_sample_duration(), consuming 100% CPU indefinitely with zero progress, leading to DoS. The loop has no iteration limit or timeout and is triggered during file open (parsing) - before any user interaction or image decoding. The process stays alive (no crash, no error logged), making it invisible to crash-based monitoring. This issue has been fixed in version 1.22.0.
A flaw was found in libheif, a HEIF and AVIF file format decoder and encoder. A remote attacker could exploit this vulnerability by providing a specially crafted HEIF (High Efficiency Image File Format) sequence file. This would trigger an infinite loop during file parsing, consuming 100% CPU indefinitely and leading to a Denial of Service (DoS) condition.
