CVE-2024-12704
Description
A flaw was found in the run-llama/llama_index. This vulnerability allows for a denial of service (DoS) attack via improper exception handling in the stream_complete method, which leads to an infinite loop in get_response_gen when the execution thread terminates abnormally.
Statement
This vulnerability marked as high severity rather than moderate due to its potential to cause a complete Denial of Service (DoS) in affected applications. This flaw can be triggered trivially by supplying an invalid input type.
Since there is no exception handling when the prediction thread terminates prematurely, the get_response_gen function enters an infinite loop, consuming CPU resources indefinitely. This not only disrupts service availability but can also impact multi-threaded environments where stalled threads accumulate, degrading overall system performance.
Mitigation
Mitigation for this issue is either not available or the currently available options do not 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).
The following CVSS metrics and score provided are preliminary and subject to review.
