CVE-2019-25623

Luminance Studio 2.17 Denial of Service via Malformed Input

Published Mar 23, 2026 CVSS 4.0 · 6.9 Medium EPSS < 1% KEV · Not listed

Description

Luminance Studio 2.17 contains a denial of service vulnerability that allows local attackers to crash the application by providing malformed input through the keyboard interface. Attackers can create a text file with arbitrary character sequences and trigger the application to process the input, causing the application to become unresponsive or terminate abnormally.

Analysis

Technical impact

Luminance Studio 2.17 suffers a denial‑of‑service condition that is triggered by malformed input entered through the keyboard interface. The flaw originates from improper handling of arbitrary character sequences, described as CWE‑641, and results in the application becoming unresponsive or terminating. Local attackers can use this to interrupt normal service.

Affected Systems

The affected product is Pixarra Luminance Studio version 2.17. Only users running this exact version on local machines are at risk, as the vulnerability requires local input.

Risk and Exploitability

The CVSS score of 6.9 indicates moderate severity, while an EPSS score below 1% and its absence from the KEV catalog imply that exploitation is unlikely in the wild. However, the attack vector is local, so any user with access to the machine can trigger the crash. The impact is an interruption of service, which can affect productivity in environments where the application is critical.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
