CVE-2018-25267

UltraISO 9.7.1.3519 Buffer Overflow via Output FileName

Published Apr 22, 2026 CVSS 4.0 · 6.9 Medium EPSS < 1% KEV · Not listed
Description
UltraISO 9.7.1.3519 contains a local buffer overflow vulnerability in the Output FileName field of the Make CD/DVD Image dialog that allows attackers to overwrite SEH and SE handler records. Attackers can craft a malicious filename string with 304 bytes of data followed by SEH record overwrite values and paste it into the Output FileName field to trigger a denial of service crash.

Analysis

AI-generated

Technical impact

UltraISO 9.7.1.3519 contains a local buffer overflow in the Output FileName field of the Make CD/DVD Image dialog; attackers can craft a 304‑byte string to overwrite Structured Exception Handler (SEH) records and cause a crash. The vulnerability allows an adversary to trigger a denial of service by simply pasting the malicious string into the dialog, without executing arbitrary code, but the denial of service can be leveraged to disrupt system availability.

Affected Systems

The affected product is UltraISO version 9.7.1.3519 for Windows; earlier version 9.35 is also listed but the specific vulnerability is reported for 9.7.1.3519. Users running this version on any Windows operating system are at risk.

Risk and Exploitability

The CVSS score of 6.9 indicates a medium severity; the EPSS score is not available, so the exploitation probability cannot be quantified, and the issue is not listed in CISA’s KEV catalog, implying no known active exploitation. The vulnerability is local, requiring an attacker to interact with the user interface or supply a crafted filename on the machine, so it is unlikely to be exploited remotely without user cooperation. Nevertheless, because it causes a crash that can affect critical processes, it should be treated as a significant risk to system availability.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Apply the latest UltraISO patch that includes bounds checking for the Output FileName field.
  • Enable or enforce input validation in the application to reject filenames exceeding the allowed buffer size (e.g., 248 bytes), mitigating CWE‑787 overflows.
  • If patching is not possible, limit the use of the Make CD/DVD Image dialog to trusted users or disable the feature altogether to reduce exposure.
