How to Fix GHSA-7jwh-3vrq-q3m8

To remediate this vulnerability, upgrade all affected Github.com/jackc/pgproto3 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/jackc/pgproto3 fixed: 2.3.3 
Upgrade github.com/jackc/pgproto3 to 2.3.3
github.com/jackc/pgproto3/v2 fixed: 2.3.3 
Upgrade github.com/jackc/pgproto3/v2 to 2.3.3
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/jackc/pgproto3

How to Check if You Are Affected

To determine whether your application is affected by GHSA-7jwh-3vrq-q3m8, inspect your project dependencies for Github.com/jackc/pgproto3:

inspect dependencies for github.com/jackc/pgproto3

Analyze the terminal output to locate any version of Github.com/jackc/pgproto3 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.3.3), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-190: Integer Overflow or Wraparound, where the product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. this occurs when an integer value is incremented to a value that is too large to store in the associated representation. when this occurs, the value may become a very small or negative number. In Github.com/jackc/pgproto3, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact SQL injection can occur if an attacker can cause a single query or bind message to exceed 4 GB in size. An integer overflow in the calculated message size can cause the one large message to be sent as multiple messages under the attacker's control. ### Patches The problem is resolved in v2.3.3 ### Workarounds Reject user input large enough to cause a single query or bind message to exceed 4 GB in size.
