CVE-2023-48221
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedwire-avs provides Audio, Visual, and Signaling (AVS) functionality sure the secure messaging software Wire. Prior to versions 9.2.22 and 9.3.5, a remote format string vulnerability could potentially allow an attacker to cause a denial of service or possibly execute arbitrary code. The issue has been fixed in wire-avs 9.2.22 & 9.3.5 and is already included on all Wire products. No known workarounds are available.

dbcve · scoped9.2.22
wire-avs version 9.2.22 (for versions < 9.2.22) or version 9.3.5 (for versions >= 9.3.0, <= 9.3.5)
- 1. Identify the current wire-avs version in use by checking the project's dependencies or version file
- 2. If the current version is < 9.2.22, plan upgrade to version 9.2.22 or later
- 3. If the current version is >= 9.3.0 and <= 9.3.5, upgrade to version 9.3.5 or later
- 4. Update the dependency in the project's dependency manifest (e.g., package.json, Podfile, or similar) to specify the fixed version
- 5. Run the package manager update command to fetch the fixed version (e.g., npm update, pod update, or similar)
- 6. Rebuild and test the application to verify the upgrade does not introduce regressions
