Meta Llama LLM security flaw could let hackers easily breach systems and spread malware

• Security researchers find way to abuse Meta's Llama LLM for remote code execution
• Meta addressed the problem in early October 2024
• The problem was using pickle as a serialization format for socket communication

Meta's Llama Large Language Model (LLM) had a vulnerability which could have allowed threat actors to execute arbitrary code on the flawed server, experts have warned.

Cybersecurity researchers from Oligo Security published an in-depth analysis about a bug tracked as CVE-2024-50050, which according to the National Vulnerability Database (NVD), carries a severity score of 6.3 (medium).

The bug was discovered in a component called Llama Stack, designed to optimize the deployment, scaling, and integration of large language models.
