CVE-2024-9676· NVD / CVE Program· CNA redhat

Podman: buildah: cri-o: symlink traversal vulnerability in the containers/storage library can cause denial of service (dos)

Noroxi assessment

Priority: Monitor (action score 26/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 1.3% (FIRST EPSS); higher than 71% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: github.com/containers/storage/ containers/storage 1.55.1; CBL Mariner 2.0 ARM 1.14.2-9; CBL Mariner 2.0 x64 1.14.2-9.

Low priority for now. Upgrade to github.com/containers/storage/ containers/storage 1.55.1; CBL Mariner 2.0 ARM 1.14.2-9; CBL Mariner 2.0 x64 1.14.2-9 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

A vulnerability was found in Podman, Buildah, and CRI-O. A symlink traversal vulnerability in the containers/storage library can cause Podman, Buildah, and CRI-O to hang and result in a denial of service via OOM kill when running a malicious image using an automatically assigned user namespace (`--userns=auto` in Podman and Buildah). The containers/storage library will read /etc/passwd inside the container, but does not properly validate if that file is a symlink, which can be used to cause the library to read an arbitrary file on the host.
