SUSE CVE-2026-32739

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 Boxstts::getsampleduration, consuming 100% CPU indefinitely with zero progress, leading to DoS. The loop has no iteration limit or timeout and...
