Severity by source
Heap overflow in a parsing utility is triggered locally by processing a crafted file (AV:L, UI:R); any user can run the tool (PR:N); memory corruption plausibly yields code execution, hence C/I/A:H, though impact is unconfirmed.

[heap buffer overflow in duplicate_legacy_root_dir]
AnalysisAI
Heap buffer overflow in an unspecified Ubuntu utility's duplicate_legacy_root_dir function can lead to high confidentiality, integrity, and availability impact when a local attacker convinces a user or automated job to process a crafted input, such as a malicious filesystem image or legacy-format file. The assessed CVSS vector (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) indicates local access, no privileges required, and user interaction as the primary limiting factor, but the exact product, affected versions, and trigger condition are unconfirmed due to the record lacking product name, CWE, EPSS, KEV, and POC data. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the affected (unnamed) utility to parse an attacker-supplied input that reaches the duplicate_legacy_root_dir code path - most plausibly a crafted filesystem image or legacy-format file processed by a local command-line tool, meaning a victim or automated job must invoke the tool on malicious data (user interaction / input delivery is the primary limiting factor). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a severely data-poor record: no CVSS score, no CVSS vector, no CWE, no EPSS, no KEV listing, and no POC reference are present in the input - the only hard facts are a function name ('duplicate_legacy_root_dir'), the bug class ('heap buffer overflow'), and that Ubuntu is the reporting vendor. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch identified at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report. |
