Given the local attack vector, required user interaction, and no integrity or availability impact in the CVSS, the blast radius is limited to the invoking user process. In centrally managed server/VM environments without interactive image-conversion tasks, the practical exploitation likelihood is minimal and this issue can be safely deprioritized.", "product_ids": [ "Ubuntu-18:giflib-tools-0:5.1.4-2ubuntu0.1+tuxcare.els1.amd64", "Ubuntu-18:giflib-tools-0:5.1.4-2ubuntu0.1.amd64", "Ubuntu-18:libgif-dev-0:5.1.4-2ubuntu0.1+tuxcare.els1.amd64", "Ubuntu-18:libgif-dev-0:5.1.4-2ubuntu0.1.amd64", "Ubuntu-18:libgif7-0:5.1.4-2ubuntu0.1+tuxcare.els1.amd64", "Ubuntu-18:libgif7-0:5.1.4-2ubuntu0.1.amd64" ] } ], "scores": [ { "cvss_v2": { "accessComplexity": "MEDIUM", "accessVector": "NETWORK", "authentication": "NONE", "availabilityImpact": "NONE", "baseScore": 4.3, "baseSeverity": "MEDIUM", "confidentialityImpact": "PARTIAL", "integrityImpact": "NONE", "vectorString": "AV:N/AC:M/Au:N/C:P/I:N/A:N", "version": "2.0" }, "cvss_v3": { "attackComplexity": "LOW", "attackVector": "LOCAL", "availabilityImpact": "NONE", "baseScore": 5.5, "baseSeverity": "MEDIUM", "confidentialityImpact": "HIGH", "integrityImpact": "NONE", "privilegesRequired": "NONE", "scope": "UNCHANGED", "userInteraction": "REQUIRED", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N", "version": "3.1" }, "products": [ "Ubuntu-18:giflib-tools-0:5.1.4-2ubuntu0.1+tuxcare.els1.amd64", "Ubuntu-18:giflib-tools-0:5.1.4-2ubuntu0.1.amd64", "Ubuntu-18:libgif-dev-0:5.1.4-2ubuntu0.1+tuxcare.els1.amd64", "Ubuntu-18:libgif-dev-0:5.1.4-2ubuntu0.1.amd64", "Ubuntu-18:libgif7-0:5.1.4-2ubuntu0.1+tuxcare.els1.amd64", "Ubuntu-18:libgif7-0:5.1.4-2ubuntu0.1.amd64" ] } ], "threats": [ { "category": "impact", "details": "Moderate" } ] } ] }
