Remote code execution during malicious image pull
Published Oct 29, 2023 · Updated Sep 9, 2024
Code injection in affected openEuler iSulad builds allows remote attackers to execute arbitrary code through a malicious image pull. The public record identifies src/utils/tar/util_archive.c and improper initialization, but the precise uninitialized state and operation remain undisclosed. Reachability requires an image pull from an attacker-controlled registry or reference; successful exploitation hijacks the image-handling process with its privileges.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <=2.0.8-20210518.144540.git5288ed93,2.0.18-10,2.1.2
