ALAS2023-2026-3155


Amazon Linux 2023 Security Advisory: ALAS2023-2026-3155
Advisory Released Date: 2026-10-12
Advisory Updated Date: 2026-10-12
Severity: Important

Issue Overview:

A flaw was found in pymongo. An integer overflow exists in the bundled native extension for Binary JSON (BSON) document encoding when processing an unusually large amount of data. An unprivileged attacker who can submit oversized data to an application for encoding can trigger an arithmetic overflow, resulting in a write outside the boundaries of an allocated memory buffer. This issue can lead to arbitrary code execution within the application process or a denial of service (DoS) via an application crash. (CVE-2026-96749)


Affected Packages:

python-pymongo


Issue Correction:
Run dnf update python-pymongo --releasever 2023.12.20261012 or dnf update --advisory ALAS2023-2026-3155 --releasever 2023.12.20261012 to update your system.
