CVE-2024-38796

What it actually does

The flaw permits memory corruption via an integer overflow in PeCoffLoaderRelocateImage during PE/COFF image relocation when triggered over an adjacent network, potentially resulting in loss of confidentiality, integrity, and availability.

Why it matters to the business

Organizations running affected Podman versions face risk of system instability, unauthorized code execution, or service outages that could disrupt container operations, though the requirement for adjacent network access and low exploitation probability limit immediate widespread impact.

How an attack unfolds

An attacker on the same local network segment crafts a malicious PE/COFF image and delivers it to a vulnerable Podman instance; during image loading the relocation routine overflows a buffer, corrupting memory and enabling further attacker-controlled actions.

How to fix it

Upgrade github.com/containers/podman/v4 (Go) to version 4.0.3 or later; where immediate upgrade is not feasible, restrict adjacent network exposure of Podman services and apply compensating controls such as network segmentation.

How to confirm the fix worked

Confirm the installed Podman version meets or exceeds 4.0.3, retest image import and relocation workflows with known-good binaries, and verify that error paths related to relocation no longer produce memory corruption indicators.

Typical attack path

1. Locate Podman instances reachable on the local network segment
2. Prepare a malformed PE/COFF binary that triggers the relocation overflow
3. Transmit the image to the target Podman process
4. Force image relocation to activate the corruption
5. Leverage corrupted memory for code execution or denial of service

How to detect it

Search Podman and system logs for relocation errors, memory allocation failures, or unexpected crashes during image processing; monitor adjacent network traffic for unusual volumes of PE/COFF files directed at Podman endpoints.

What your security team should do

• Apply the 4.0.3 update at the earliest maintenance window given the integrity impact
• Segment Podman hosts from untrusted adjacent networks
• Add Podman version checks to asset inventories and vulnerability scanners
• Review container image sources to reduce exposure to untrusted binaries
