SCA: security update for Npgsql (GHSA-x9vc-6hfv-hg8c)

high Tenable Cloud Security Plugin ID 420413

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Npgsql is the .NET data provider for PostgreSQL. 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. This vulnerability is
 fixed in 4.0.14, 4.1.13, 5.0.18, 6.0.11, 7.0.7, and 8.0.3. (CVE-2024-32655)
