AI-Generated

Versions 1.19.0 to 1.21.2 of libheif are vulnerable to a heap out-of-bounds read due to a tile-coordinate underflow in the ImageItem_Grid::decode_grid_tile function, potentially allowing attackers to access sensitive memory contents. This vulnerability poses a high risk, particularly for applications that utilize libheif for handling HEIF and AVIF file formats. Organizations using affected versions should prioritize upgrading to version 1.22.0 to mitigate the risk of exploitation.
