Impact

A vulnerability exists in the Qt Quick framework’s Context2D.path and PathSvg.path properties, allowing an out‑of‑bounds read while parsing SVG path strings from untrusted sources. This flaw can lead to leakage of the running process’s memory contents, potentially exposing sensitive data to an attacker who can supply crafted SVG data.

Affected Systems

The issue affects the Qt framework (qt:qt) on all builds that include Qt Quick’s SVG handling. No specific product or version range is listed in the CNA data, so the vulnerability applies to any Qt installation that utilizes Context2D.path or PathSvg.path without further context in the provided information.

Risk and Exploitability

The CVSS score of 0.6 indicates a low impact concern. No EPSS data is available, and the vulnerability is not listed in CISA’s KEV catalog, suggesting limited known exploitation. The likely attack vector involves sending malicious SVG content to an application that processes such files directly. Because the flaw does not grant code execution or privilege escalation, the immediate risk to confidentiality is relatively mild, but memory disclosure can be leveraged in certain side‑channel or credential‑extraction scenarios.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Update Qt to the latest version that contains the fix for the Context2D.path and PathSvg.path out‑of‑bounds read issue.
  • Validate all SVG path strings on input, ensuring they conform to expected length and format before passing them to Context2D.path or PathSvg.path, which implements proper bounds checking.
  • If a patch cannot be applied immediately, restrict or disable processing of SVG files from untrusted sources, or render SVG content in a sandboxed environment to contain any potential memory leaks.
