The attack is not remotely exploitable in isolation and depends on a user or service processing attacker-controlled input.\n\nFurthermore, the impact of the vulnerability is limited to the privileges of the extracting process. In typical Red Hat deployments, archive extraction is performed by non-privileged users or within confined environments such as containers or restricted service contexts, which limits the scope of potential damage.\n\nRed Hat analysis also notes that this issue does not provide a direct mechanism for code execution or privilege escalation, but rather enables file system manipulation within the boundaries of the executing user\u2019s permissions.\n\nGiven the requirement for user-assisted exploitation, the absence of a direct remote attack vector, and the confinement of impact to the privileges of the extracting process, Red Hat considers the practical risk to be lower than the generalized NVD assessment. As a result, this vulnerability is classified as Moderate severity.",
