strukturag.libheif is vulnerable to Denial of Service (DoS)
69
Medium Risk
This Affects:
strukturag.libheifTL;DR
libheif allocates a heif_raw_sequence_sample with a deep-copied payload before several error-return paths in Track::get_next_sample_raw_data, and those paths return an error variant that cannot carry the pointer back, leaking the object and its payload on every error. The C entry point also lacks an exception guard, so an allocation failure can cross the extern "C" boundary and terminate the process. Repeatedly reading raw sequence samples from a crafted file exhausts memory or aborts. The fix uses owning pointers and adds an exception guard at the entry point.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and your application reads raw sequence samples through the heif_track_get_next_raw_sequence_sample API.
