CVE-2024-3044
Description
A flaw was found in LibreOffice. Unchecked script execution in graphic on-click binding allows an attacker to create a document, which, without a prompt, will execute scripts built into LibreOffice when clicking a graphic. These scripts were previously deemed trusted but are now deemed untrusted.
Statement
CVE-2024-3044 poses a Moderate severity risk due to its potential to enable unauthorized script execution within LibreOffice documents. While the vulnerability allows for the execution of untrusted scripts upon clicking graphics, it requires user interaction to initiate. Furthermore, the impact is constrained by the user's explicit macro execution permissions, determined at document load time. Although the flaw could lead to unintended script execution, its impact is mitigated by the necessity for user interaction and the reliance on explicit macro permissions.
Mitigation
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)
Availability
Technical Impact: DoS: Crash, Exit, or Restart; DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory)
An attacker could provide unexpected values and cause a program crash or arbitrary control of resource allocation, leading to excessive consumption of resources such as memory and CPU.
Confidentiality
Technical Impact: Read Memory; Read Files or Directories
An attacker could read confidential data if they are able to control resource references.
Integrity,Confidentiality,Availability
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands
An attacker could use malicious input to modify data or possibly alter control flow in unexpected ways, including arbitrary command execution.
