**Nome do software vulnerável e versões afetadas** Podman, Buildah e CRI-O (versões afetadas não especificadas) **Descrição** Uma vulnerabilidade de traversal de link simbólico na biblioteca containers/storage pode fazer com que o Podman, o Buildah e o CRI-O travem e resultar em uma negação de serviço via OOM kill ao executar uma imagem maliciosa usando um namespace de usuário atribuído automaticamente (`--userns=auto` no Podman e no Buildah). A biblioteca containers/storage lê o arquivo /etc/passwd dentro do contêiner, mas não valida corretamente se esse arquivo é um link simbólico, o que pode ser usado para fazer com que a biblioteca leia um arquivo arbitrário no host. Essa vulnerabilidade pode ser explorada por um invasor remoto para causar uma negação de serviço usando um link simbólico especialmente criado para um arquivo arbitrário no sistema. **Recomendações** No momento, não há informações sobre uma versão mais recente que contenha uma correção para essa vulnerabilidade.

**Name of the Vulnerable Software and Affected Versions** Kubernetes versions 1.1 through 1.12 Kubernetes versions prior to 1.13.11 Kubernetes versions prior to 1.14.7 Kubernetes versions prior to 1.15.4 **Description** The issue is related to the Kubernetes kubectl cp command, which allows an attacker to place a malicious file outside of the destination directory using a combination of symlinks provided by tar output of a malicious container. This could enable an attacker to upload a nefarious file using a symlink, outside of the destination tree. The vulnerability is associated with incorrect link resolution before accessing a file, which may allow a remote attacker to upload a malicious file. **Recommendations** For versions 1.1 through 1.12, update to a version prior to 1.13.11, 1.14.7, or 1.15.4 to resolve the issue. For versions prior to 1.13.11, update to version 1.13.11 or later. For versions prior to 1.14.7, update to version 1.14.7 or later. For versions prior to 1.15.4, update to version 1.15.4 or later. As a temporary workaround, consider restricting the use of the kubectl cp command until a patch is available.
