0.7.4->0.8.1GitHub Vulnerability Alerts
GHSA-xmrp-424f-vfpx
The following presentation at this year's DEF CON was brought to our attention on the SQLx Discord:
Essentially, encoding a value larger than 4GiB can cause the length prefix in the protocol to overflow,
causing the server to interpret the rest of the string as binary protocol commands or other data.
It appears SQLx does perform truncating casts in a way that could be problematic,
for example: https://github.com/launchbadge/sqlx/blob/6f2905695b9606b5f51b40ce10af63ac9e696bb8/sqlx-postgres/src/arguments.rs#L163
This code has existed essentially since the beginning,
so it is reasonable to assume that all published versions
<= 0.8.0are affected.Mitigation
As always, you should make sure your application is validating untrustworthy user input.
Reject any input over 4 GiB, or any input that could encode to a string longer than 4 GiB.
Dynamically built queries are also potentially problematic if it pushes the message size over this 4 GiB bound.
Encode::size_hint()can be used for sanity checks, but do not assume that the size returned is accurate.
For example, the
Json<T>andText<T>adapters have no reasonable way to predict or estimate the final encoded size,so they just return
size_of::<T>()instead.For web application backends, consider adding some middleware that limits the size of request bodies by default.
Resolution
Work has started on a branch to add
#[deny]directives for the following Clippy lints:cast_possible_truncationcast_possible_wrapcast_sign_lossand to manually audit the code that they flag.
A fix is expected to be included in the
0.8.1release (still WIP as of writing).Release Notes

This release contains a fix for RUSTSEC-2024-0363.
Postgres users are advised to upgrade ASAP as a possible exploit has been demonstrated:

MySQL and SQLite do not appear to be exploitable, but upgrading is recommended nonetheless.
