CRITICAL 9.8REMOTEUPGRADE

CVE-2024-3271 is a critical-severity flaw (CVSS 9.8) affecting llamaindex. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

A command injection vulnerability exists in the run-llama/llama_index repository, specifically within the safe_eval function. Attackers can bypass the intended security mechanism, which checks for the presence of underscores in code generated by LLM, to execute arbitrary code. This is achieved by crafting input that does not contain an underscore but still results in the execution of OS commands. The vulnerability allows for remote code execution

llamaindex llamaindex UPGRADE

Affected: >= 0.10.6 and < 0.10.26

Fixed in: 0.10.26

Safe to downgrade to: a release before 0.10.6

1. Check installed version

apt-cache policy llamaindex || rpm -q llamaindex || llamaindex --version

2. UPGRADE to 0.10.26 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade llamaindex

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade llamaindex

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 0.10.6 (Debian / Ubuntu)

apt-cache madison llamaindex sudo apt install llamaindex=<VERSION_BEFORE_0.10.6> sudo apt-mark hold llamaindex

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list llamaindex sudo dnf downgrade llamaindex-<VERSION_BEFORE_0.10.6> sudo dnf versionlock add llamaindex

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
