DEBIAN-CVE-2026-32882

libheif is a HEIF and AVIF file format decoder and encoder. Versions 1.21.2 and prior contain a heap buffer over-read in HeifPixelImage::overlay in libheif/pixelimage.cc. When compositing an overlay image iovl whose child image has a different bit depth for the alpha channel than for the color...

CVE-2026-32741

libheif is a HEIF and AVIF file format decoder and encoder. Versions 1.21.2 and below contain a heap buffer overflow in MaskImageCodec::decodemaskimage. When decoding a HEIF file containing a mask image mski, the function copies the full iloc extent data into a pixel buffer using memcpydst,...

CVE-2026-32814

libheif is a HEIF and AVIF file format decoder and encoder. In versions 1.21.2 and prior, when decoding a HEIF grid image with strictdecoding=false the default, a corrupted tile silently fails to decode and the library returns heiferrorOk with no indication of failure, leading to an uninitialized...

ALPINE-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...
