Ecosyste.ms: Advisories

An open API service providing security vulnerability metadata for many open source software ecosystems.

Security Advisories: GSA_kwCzR0hTQS1wcXdoLWMyZjMtdnhtcc4AAzw9

Untrusted data fed into `Data.init(base32Encoded:)` can result in exposing server memory and/or crash

Impact

A bug in the Data.init(base32Encoded:) function opens up the potential for exposing server memory and/or crashing the server (Denial of Service) for applications where untrusted data can end up in said function. Vapor does not currently use this function itself so this only impact applications that use the impacted function directly or through other dependencies.

Patches

This issue has been patched in 4.47.2.

Workarounds

Use an alternative to Vapor's built-in Data.init(base32Encoded:).
