CVE-2026-6045
Description
A flaw was found in LibreOffice. A heap buffer overflow exists when importing EMF+ graphics, which may be embedded in documents. An attacker could exploit this by convincing a user to open a specially crafted document. This could lead to denial of service or memory corruption, potentially allowing for arbitrary code execution.
Statement
Moderate impact. This heap buffer overflow in LibreOffice's EMF+ graphics import requires user interaction to open a malicious document. While it could lead to denial of service or arbitrary code execution, the need for user interaction and the specific file format limits its immediate widespread impact on Red Hat Enterprise Linux desktop environments.
Mitigation
To reduce the risk of exploitation, users should avoid opening untrusted or suspicious documents with LibreOffice. This vulnerability requires user interaction to trigger the heap buffer overflow. While specific configuration to disable EMF+ graphics processing may not be readily available, running LibreOffice in a sandboxed environment can help limit the impact of a successful attack.
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).
The following CVSS metrics and score provided are preliminary and subject to review.
