strukturag.libheif is vulnerable to Uncontrolled Resource Consumption
75
High Risk
This Affects:
strukturag.libheifTL;DR
libheif follows chains of derived-image references such as grid, overlay, and identity items without caching decode results or accounting for the allocations. A file with indirect reference chains forces a base image to be decoded hundreds of times and pre-allocates large tile-offset vectors outside the memory budget. Opening or decoding such a file leads to denial of service. The fix adds decode-result caching and enforces memory limits on the affected allocations.
Who does this affect?
You are affected if you decode untrusted HEIF files with a vulnerable version.
