CVE-2025-5683
Description
A flaw was found in qt. Loading a specially crafted ICNS image file within QImage results in a crash. This flaw allows a local attacker to provide a malicious image. The vulnerability is exploited via the image loading process, leading to application termination.
Statement
The vulnerability involves a crash triggered by a specifically crafted ICNS image file within QImage. While the attack vector is remote (AV:N) and requires no authentication (PR:N), user interaction (UI:R) is necessary to load the malicious image. This limits the ease of exploitation compared to vulnerabilities that allow for fully automated remote code execution. A crash, while disruptive, doesn’t inherently lead to arbitrary code execution or data compromise. However, a denial of service is possible, and a determined attacker could potentially exploit the crash to gain further information or potentially escalate to a more severe outcome. Given the ubiquity of Qt in various applications, a crash vulnerability warrants a Moderate rating. The lack of authentication and remote attack vector are mitigating factors, but the potential for denial of service and the wide usage of Qt contribute to the overall risk.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Availability
Technical Impact: DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory); DoS: Resource Consumption (Other)
When allocating resources without limits, an attacker could prevent other systems, applications, or processes from accessing the same type of resource. It can be easy for an attacker to consume many resources by rapidly making many requests or causing larger resources to be used than is needed.
