Chainguard: multiple localstack packages: security update to 4.14.0-r29

high Tenable Self-Hosted Container Security Plugin ID 473508

Description

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

 - An integer overflow in the BSON document encoding component of the MongoDB Python Driver's bundled native
 extension may occur when a single document is built from an unusually large amount of caller-supplied
 data. Size arithmetic is performed in a signed 32-bit type, and the guard meant to catch the overflow is
 written in a form whose behavior is not defined by the C language standard. A party with no privileges who
 can place a very large value into data that an application encodes may, depending on how the native
 extension was built, cause a write outside the bounds of an allocated buffer inside the application's own
 process. (CVE-2026-96749)

Solution

Update the localstack library and its related packages to version 4.14.0-r29 or later.
