Struktur Libheif

libheif 1.4.0 has a use-after-free in heif::HeifContext::Image::set_alpha_channel in heif_context.h because heif_context.cc mishandles references to non-existing alpha images.

An issue was discovered in heif::Box_iref::get_references in libheif 1.4.0, allows attackers to cause a Denial of Service or possibly other unspecified impact due to an invalid memory read.

Floating point exception in function Fraction in libheif 1.4.0, allows attackers to cause a Denial of Service or possibly other unspecified impacts.

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 find_exif_tag at /libheif/exif.cc.

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

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

libheif: Heap-Buffer-Overflow Write in Grid Tile Chroma Compositing

Buffer overflow vulnerability in function convert_colorspace in heif_colorconversion.cc in libheif v1.6.2, allows attackers to cause a denial of service and disclose sensitive information, via a crafted HEIF file.

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: Heap buffer over-read in SampleAuxInfoReader via crafted HEIF sequence file with mismatched saiz sample count

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 buffer overflow in linear memory during a memcpy call.

libheif has Heap Out Of Bounds Write in unci subsystem

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 Vulnerable to Heap Information Disclosure via Grid Image Gap + Uninitialized Pixel Plane Allocation

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.

libheif: heap OOB read in ImageItem_Grid::decode_grid_tile via irot-induced tile-coordinate underflow

libheif has Potential Heap Buffer Over-Read

libheif has a NULL pointer dereference in heif_image_handle_get_image_tiling for malformed unci image missing ispe

libheif has an incomplete fix for CVE-2026-3949: integer overflow bypass in vvdec_push_data2

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 denial of service.

libheif allows Out-of-bounds vector access leading to invalid dereference (DoS)

libheif is Vulnerable to Infinite Loop DoS via stts Sample Duration Lookup

libheif has a Heap OOB Read/SEGV Crash via Zero samples_per_chunk

libheif: Wrapped icef compressed-unit range check causes out-of-bounds read in uncompressed HEIF decoder

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.

libheif Has Heap Buffer Overflow in `Track::get_next_sample_raw_data()` -- OOB Chunk Vector Access

libheif has integer overflow in inline mask size calculation that causes undersized buffer allocation
