CVE-2024-12886
Description
A flaw was found in Ollama. This vulnerability allows a denial of service (DoS) condition via excessive memory consumption when a malicious API server responds with a gzip bomb HTTP response. The makeRequestWithRetry and getAuthorizationToken functions use io.ReadAll to read the response body, which leads to out-of-memory crashes.
Statement
Ansible LightSpeed does not use Ollama server. The library is included in the image just for local development or testing.
Mitigation
Implementing input validation to restrict the types of GZIP data accepted by the application would help to mitigate the risk of exploitation.
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.
