No implementations of `get_slice` provided in `vm_memory` are affected. Users of custom `VolatileMemory` implementations may be impacted if the custom implementation does not adhere to `get_slice`'s documentation.\n\nThe issue started in version 0.1.0 but was fixed in version 0.12.2 by inserting a check that verifies that the `VolatileSlice` returned by `get_slice` is of the correct length.","affected":[{"package":{"name":"vm-memory","ecosystem":"crates.io","purl":"pkg:cargo/vm-memory"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0.0.0-0"},{"fixed":"0.12.2"}]}],"ecosystem_specific":{"affected_functions":null,"affects":{"arch":[],"functions":["vm_memory::volatile_memory::VolatileMemory::aligned_as_mut","vm_memory::volatile_memory::VolatileMemory::aligned_as_ref","vm_memory::volatile_memory::VolatileMemory::get_array_ref","vm_memory::volatile_memory::VolatileMemory::get_atomic_ref","vm_memory::volatile_memory::VolatileMemory::get_ref"],"os":[]}},"database_specific":{"categories":["memory-exposure"],"cvss":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:L","informational":"unsound","source":"https://github.com/rustsec/advisory-db/blob/osv/crates/RUSTSEC-2023-0056.json"}}],"references":[{"type":"PACKAGE","url":"https://crates.io/crates/vm-memory"},{"type":"ADVISORY","url":"https://rustsec.org/advisories/RUSTSEC-2023-0056.html"},{"type":"REPORT","url":"https://github.com/rust-vmm/vm-memory/issues/250"},{"type":"WEB","url":"https://github.com/rust-vmm/vm-memory/commit/aff1dd4a5259f7deba56692840f7a2d9ca34c9c8"}],"database_specific":{"license":"CC0-1.0"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:L"}]} |
