### Impact SQL injection is possible when using the non-default connection property `preferQueryMode=simple` in combination with application code which has a vulnerable SQL that negates a parameter value. There is no vulnerability in the driver when using the default, extended query mode. Note that `preferQueryMode` is not a supported parameter in Redshift JDBC driver, and is inherited code from Postgres JDBC driver. Users who do not override default settings to utilize this unsupported query mode are not affected. ### Patch This issue is patched in driver version 2.1.0.28. ### Workarounds Do not use the connection property `preferQueryMode=simple`. (NOTE: If you do not explicitly specify a query mode, then you are using the default of extended query mode and are not affected by this issue.) ### References Similar to finding in Postgres JDBC: https://github.com/pgjdbc/pgjdbc/security/advisories/GHSA-24rp-q3w6-vc56 If you have any questions or comments about this advisory, we a...

### Summary The `WriteBind()` method in `src/Npgsql/Internal/NpgsqlConnector.FrontendMessages.cs` uses `int` variables to store the message length and the sum of parameter lengths. Both variables overflow when the sum of parameter lengths becomes too large. This causes Npgsql to write a message size that is too small when constructing a Postgres protocol message to send it over the network to the database. When parsing the message, the database will only read a small number of bytes and treat any following bytes as new messages while they belong to the old message. Attackers can abuse this to inject arbitrary Postgres protocol messages into the connection, leading to the execution of arbitrary SQL statements on the application's behalf. ### Details Please see [this attached PDF file](https://github.com/npgsql/npgsql/files/14309386/Npgsql.Security.Advisory.pdf) for a detailed description, including the suspected root cause, exploitation steps, impact, and recommendations on for fixin...

As part of its Secure by Design initiative, CISA urged companies to redouble efforts to quash SQL injection vulnerabilities. Here's how.

The malicious code inserted into the open-source library XZ Utils, a widely used package present in major Linux distributions, is also capable of facilitating remote code execution, a new analysis has revealed. The audacious supply chain compromise, tracked as CVE-2024-3094 (CVSS score: 10.0), came to light last week when Microsoft engineer and PostgreSQL developer Andres Freund
