libheif is a HEIF and AVIF file format decoder and encoder. In versions 1.21.2 and prior, a malformed HEIF sequence file can trigger an out-of-bounds read in core sequence parsing…

libheif is a HEIF and AVIF file format decoder and encoder. Versions 1.21.2 and prior contain a heap-buffer-overflow (write) vulnerability in the grid tile compositing, allowing a…

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_dur…

libheif is a HEIF and AVIF file format decoder and encoder. In versions 1.21.2 and below, a crafted 792-byte HEIF sequence file with samples_per_chunk=0 in the stsc box causes an…

libheif is an HEIF and AVIF file format decoder and encoder. Prior to version 1.21.0, a crafted HEIF that exercises the overlay image item path triggers a heap buffer over-read in…

libheif before 1.19.6 has a NULL pointer dereference in ImageItem_Grid::get_decoder in image-items/grid.cc because a grid image can reference a nonexistent image item.

libheif before 1.19.6 has a NULL pointer dereference in ImageItem_iden in image-items/iden.cc.

Buffer Overflow vulnerability in libheif 1.19.7 allows a local attacker to execute arbitrary code via the SAO (Sample Adaptive Offset) processing of libde265.

In Libheif 1.17.6, insufficient checks in ImageOverlay::parse() decoding a heif file containing an overlay image with forged offsets can lead to an out-of-bounds read and write.

libheif <= 1.17.6 contains a memory leak in the function JpegEncoder::Encode. This flaw allows an attacker to cause a denial of service attack.

libheif v1.17.5 was discovered to contain a segmentation violation via the function UncompressedImageCodec::get_luma_bits_per_pixel_from_configuration_unci.

libheif v1.17.5 was discovered to contain a segmentation violation via the function find_exif_tag at /libheif/exif.cc.

libheif v1.17.5 was discovered to contain a segmentation violation via the component /libheif/exif.cc.

libheif v1.17.5 was discovered to contain a segmentation violation via the function UncompressedImageCodec::decode_uncompressed_image.

A Segmentation fault caused by a floating point exception exists in libheif 1.15.1 using crafted heif images via the heif::Fraction::round() function in box.cc, which causes a den…

There is a vulnerability in the strided image data parsing code in the emscripten wrapper for libheif. An attacker could exploit this through a crafted image file to cause a buffe…
