  "details": "### Summary\n\ndiesel-async exposes uninitialized stack padding to safe code on every read of a MySQL `DATE`, `TIME`, `DATETIME`, or `TIMESTAMP` column. Reading that buffer is undefined behavior, and the leaked bytes can contain stale heap/stack contents, so this is both a soundness bug and a potential information-disclosure vector.\n\n### Details\n\nIn `diesel-async/src/mysql/row.rs` (lines 65-103), `MysqlRow::get` builds a `MysqlTime` from the parsed `mysql_async::Value` and then fabricates the byte buffer that downstream `FromSql` impls expect like this:\n\n```rust\nlet date = MysqlTime::new(/* fields from Value::Date / Value::Time */);\nlet buffer = unsafe {\n    let ptr = \u0026date as *const MysqlTime as *const u8;\n    let slice = std::slice::from_raw_parts(ptr, std::mem::size_of::\u003cMysqlTime\u003e());\n    slice.to_vec()\n};\n```\n\n`MysqlTime` is `#[repr(C)]` with 3 bytes of padding after `bool neg` (Linux x86_64, offsets 0x21..0x23). The literal construction leaves that padding uninitialized, and `to_vec()` carries it into a `Vec\u003cu8\u003e` that becomes the `MysqlValue`\u0027s backing buffer, reachable from safe code via `MysqlValue::as_bytes() -\u003e \u0026[u8]`.\n\n`diesel` itself avoids this by going through `MaybeUninit::\u003cMysqlTime\u003e::zeroed()` + `ptr::copy_nonoverlapping` (see `diesel/src/mysql/value.rs:43-94`); the same pattern would fix this. Alternatively, write the bytes diesel\u0027s `FromSql` reads without round-tripping through a `MysqlTime` value.\n\n### PoC\n\n`Cargo.toml`:\n```toml\n[dependencies]\ndiesel = { version = \"~2.3.0\", default-features = false, features = [\"mysql_backend\"] }\ndiesel-async = { version = \"=0.8.0\", features = [\"mysql\"] }\nmysql_common = { version = \"0.35\", default-features = false }\n```\n\n`src/main.rs`:\n```rust\nuse diesel::row::{Field, Row};\nuse diesel_async::{AsyncConnectionCore, AsyncMysqlConnection};\nuse mysql_common::{constants::ColumnType, packets::Column, prelude::FromRow, value::Value};\n\ntype MysqlRow = \u003cAsyncMysqlConnection as AsyncConnectionCore\u003e::Row\u003c\u0027static, \u0027static\u003e;\n\nfn main() {\n    let cols = std::sync::Arc::from([Column::new(ColumnType::MYSQL_TYPE_DATE)]);\n    let raw = mysql_common::row::new_row(vec![Value::Date(2024, 1, 1, 0, 0, 0, 0)], cols);\n    let row: MysqlRow = FromRow::from_row(raw);\n\n    let field = row.get(0).unwrap();\n    let bytes = field.value().unwrap().as_bytes();\n    let _: u64 = bytes.iter().map(|\u0026b| b as u64).sum(); // UB: hits padding\n}\n```\n\nMiri output:\n\n```\nerror: Undefined Behavior: reading memory at alloc844[0x21..0x22], but memory is uninitialized at [0x21..0x22], and this operation requires initialized memory\n  --\u003e src/main.rs:14:37\n   |\n14 |     let _: u64 = bytes.iter().map(|\u0026b| b as u64).sum(); // UB: hits padding\n   |                                     ^ Undefined Behavior occurred here\n   |\n   = help: this indicates a bug in the program: it performed an invalid operation, and caused Undefined Behavior\n   = help: see https://doc.rust-lang.org/nightly/reference/behavior-considered-undefined.html for further information\n   = note: stack backtrace:\n           0: main::{closure#0}\n               at src/main.rs:14:37: 14:38\n           1: std::iter::adapters::map::map_fold::\u003c\u0026u8, u64, u64, {closure@src/main.rs:14:35: 14:39}, {closure@\u003cu64 as std::iter::Sum\u003e::sum\u003cstd::iter::Map\u003cstd::slice::Iter\u003c\u0027_, u8\u003e, {closure@src/main.rs:14:35: 14:39}\u003e\u003e::{closure#0}}\u003e::{closure#0}\n               at /home/paolobarbolini/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/src/rust/library/core/src/iter/adapters/map.rs:88:28: 88:34\n           2: \u003cstd::slice::Iter\u003c\u0027_, u8\u003e as std::iter::Iterator\u003e::fold::\u003cu64, {closure@std::iter::adapters::map::map_fold\u003c\u0026u8, u64, u64, {closure@src/main.rs:14:35: 14:39}, {closure@\u003cu64 as std::iter::Sum\u003e::sum\u003cstd::iter::Map\u003cstd::slice::Iter\u003c\u0027_, u8\u003e, {closure@src/main.rs:14:35: 14:39}\u003e\u003e::{closure#0}}\u003e::{closure#0}}\u003e\n               at /home/paolobarbolini/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/src/rust/library/core/src/slice/iter/macros.rs:279:27: 279:85\n           3: \u003cstd::iter::Map\u003cstd::slice::Iter\u003c\u0027_, u8\u003e, {closure@src/main.rs:14:35: 14:39}\u003e as std::iter::Iterator\u003e::fold::\u003cu64, {closure@\u003cu64 as std::iter::Sum\u003e::sum\u003cstd::iter::Map\u003cstd::slice::Iter\u003c\u0027_, u8\u003e, {closure@src/main.rs:14:35: 14:39}\u003e\u003e::{closure#0}}\u003e\n               at /home/paolobarbolini/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/src/rust/library/core/src/iter/adapters/map.rs:128:9: 128:50\n           4: \u003cu64 as std::iter::Sum\u003e::sum::\u003cstd::iter::Map\u003cstd::slice::Iter\u003c\u0027_, u8\u003e, {closure@src/main.rs:14:35: 14:39}\u003e\u003e\n               at /home/paolobarbolini/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/src/rust/library/core/src/iter/traits/accum.rs:52:17: 56:18\n           5: \u003cstd::iter::Map\u003cstd::slice::Iter\u003c\u0027_, u8\u003e, {closure@src/main.rs:14:35: 14:39}\u003e as std::iter::Iterator\u003e::sum::\u003cu64\u003e\n               at /home/paolobarbolini/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/src/rust/library/core/src/iter/traits/iterator.rs:3676:9: 3676:23\n           6: main\n               at src/main.rs:14:18: 14:55\n\nUninitialized memory occurred at alloc844[0x21..0x22], in this allocation:\nalloc844 (Rust heap, size: 48, align: 1) {\n    0x00 \u2502 e8 07 00 00 01 00 00 00 01 00 00 00 00 00 00 00 \u2502 ................\n    0x10 \u2502 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 \u2502 ................\n    0x20 \u2502 00 __ __ __ 01 00 00 00 00 00 00 00 __ __ __ __ \u2502 .\u2591\u2591\u2591........\u2591\u2591\u2591\u2591\n}\n```\n\n### Impact\n\nSoundness bug in safe API surface of `diesel-async`\u0027s MySQL backend.
