  "title": "firefox: crossbeam-utils provides atomics, synchronization primitives, scopedthreads, and other utilities for concurrent progr...",
  "description": "crossbeam-utils provides atomics, synchronization primitives, scopedthreads, and other utilities for concurrent programming in Rust.crossbeam-utils prior to version 0.8.7 incorrectly assumed that thealignment of \u0060{i,u}64\u0060 was always the same as \u0060Atomic{I,U}64\u0060. However, thealignment of \u0060{i,u}64\u0060 on a 32-bit target can be smaller than\u0060Atomic{I,U}64\u0060. This can cause unaligned memory accesses and data race.Crates using \u0060fetch_*\u0060 methods with \u0060AtomicCell\u003C{i,u}64\u003E\u0060 are affected bythis issue. 32-bit targets without \u0060Atomic{I,U}64\u0060 and 64-bit targets arenot affected by this issue. This has been fixed in crossbeam-utils 0.8.7.There are currently no known workarounds.",
