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 denial of service.

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.

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.

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.
