CVE-2025-0317
Description
A flaw was found in Ollama. This vulnerability allows a malicious user to upload and create a customized GGUF model file on the Ollama server, leading to a division by zero error in the ggufPadding function. This causes the server to crash, resulting in a denial of service (DoS) attack.
Statement
Ansible LightSpeed does not use Ollama server. The library is included in the image just for local development or testing.
Mitigation
Implementing an input validation to check a valid model file formats before processing would help to mitigate this issue.
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.
