Merge remote-tracking branch 'origin/main' into look-behind-regex

Update Rust crate wasmtime to v24.0.2 [SECURITY] (#20262 )
This PR contains the following updates: | Package | Type | Update | Change | |---|---|---|---| | [wasmtime](https://redirect.github.com/bytecodealliance/wasmtime) | workspace.dependencies | patch | `24.0.1` -> `24.0.2` | ### GitHub Vulnerability Alerts #### [CVE-2024-51745](https://redirect.github.com/bytecodealliance/wasmtime/security/advisories/GHSA-c2f5-jxjv-2hh8) ### Impact Wasmtime's filesystem sandbox implementation on Windows blocks access to special device filenames such as "COM1", "COM2", "LPT0", "LPT1", and so on, however it did not block access to the special device filenames which use superscript digits, such as "COM¹", "COM²", "LPT⁰", "LPT¹", and so on. Untrusted Wasm programs that are given access to any filesystem directory could bypass the sandbox and access devices through those special device filenames with superscript digits, and through them gain access peripheral devices connected to the computer, or network resources mapped to those devices. This can include modems, printers, network printers, and any other device connected to a serial or parallel port, including emulated USB serial ports. ### Patches Patch releases for Wasmtime have been issued as 24.0.2, 25.0.3, and 26.0.1. Users of Wasmtime 23.0.x and prior are recommended to upgrade to one of these patched versions. ### Workarounds There are no known workarounds for this issue. Affected Windows users are recommended to upgrade. ### References - [Microsoft's documentation](https://learn.microsoft.com/en-us/windows/win32/fileio/naming-a-file#naming-conventions) of the special device filenames - [ISO-8859-1](https://en.wikipedia.org/wiki/ISO/IEC_8859-1) - [The original PR reporting the issue](https://redirect.github.com/bytecodealliance/cap-std/pull/371) --- ### Release Notes <details> <summary>bytecodealliance/wasmtime (wasmtime)</summary> ### [`v24.0.2`](https://redirect.github.com/bytecodealliance/wasmtime/releases/tag/v24.0.2) [Compare Source](https://redirect.github.com/bytecodealliance/wasmtime/compare/v24.0.1...v24.0.2) #### 24.0.2 Released 2024-11-05. ##### Fixed - Update to cap-std 3.4.1, for [#9559](https://redirect.github.com/bytecodealliance/wasmtime/issues/9559), which fixes a wasi-filesystem sandbox escape on Windows. [CVE-2024-51745](https://redirect.github.com/bytecodealliance/wasmtime/security/advisories/GHSA-c2f5-jxjv-2hh8). </details> --- ### Configuration 📅 **Schedule**: Branch creation - "" in timezone America/New_York, Automerge - At any time (no schedule defined). 🚦 **Automerge**: Disabled by config.

+// Invisibility in a Unicode context is not well defined, so we have to guess.

+// We highlight all ASCII control codes, and unicode whitespace because they are likely
+// confused with an ASCII space in a programming context (U+0020).
+//
+// We also highlight the handful of blank non-space characters:
+//   U+2800 BRAILLE PATTERN BLANK - Category: So
+//   U+115F HANGUL CHOSEONG FILLER - Category: Lo
+//   U+1160 HANGUL CHOSEONG FILLER - Category: Lo
+//   U+3164 HANGUL FILLER - Category: Lo
+//   U+FFA0 HALFWIDTH HANGUL FILLER - Category: Lo
+//   U+FFFC OBJECT REPLACEMENT CHARACTER - Category: So
+//
+// For the rest of Unicode, invisibility happens for two reasons:
+// * A Format character (like a byte order mark or right-to-left override)
+// * An invisible Nonspacing Mark character (like U+034F, or variation selectors)
+//
+// We don't consider unassigned codepoints invisible as the font renderer already shows
+// a replacement character in that case (and there are a *lot* of them)
+//
+// Control characters are mostly fine to highlight; except:
+// * U+E0020..=U+E007F are used in emoji flags. We don't highlight them right now, but we could if we tightened our heuristics.
+// * U+200D is used to join characters. We highlight this but don't replace it. As our font system ignores mid-glyph highlights this mostly works to highlight unexpected uses.
+//
+// Nonspacing marks are handled like U+200D. This means that mid-glyph we ignore them, but
