SEGV on unknown address due to vulnerability in heif-forked lib

[Nalen98]

Greetings.
I researched this repo and crafted the malformed input which leads to crash at ItemDataBox::read(std::vector<unsigned char, std::allocator<unsigned char> >&, unsigned long, unsigned long) in lib/heif/Srcs/common/itemdatabox.cpp:25.
