Uninitialized memory access in Motoko incremental garbage collector
Résumé
Uninitialized memory access in Motoko incremental garbage collector
Description d'origine
La description telle que publiée par la source (souvent en anglais).
Motoko's incremental garbage collector is impacted by an uninitialized memory access bug, caused by incorrect use of write barriers in a few locations. This vulnerability could potentially allow unauthorized read or write access to a Canister's memory. However, exploiting this bug requires the Canister to enable the incremental garbage collector or enhanced orthogonal persistence, which are non-default features in Motoko.
