CyberRota Analysis
AI-GeneratedThe Gosub browser engine is vulnerable to uncontrolled recursion, allowing remote attackers to exploit SVG documents with excessive nesting, leading to Denial of Service through stack exhaustion and application crashes. This vulnerability can be easily exploited by embedding malicious SVGs in web pages, requiring only that users visit the compromised site. Organizations using the Gosub engine should prioritize patching this issue to mitigate potential service disruptions.

Original NVD Description
Uncontrolled recursion in the Gosub browser engine (gosub-engine) through 0.1.0 and main before commit 46868b3 allows a remote attacker to cause a Denial of Service (stack exhaustion and application crash) via an SVG document containing an excessive number of deeply nested elements. Because the engine does not limit the nesting depth of processed SVG nodes, rendering such a document overflows the thread stack and terminates the application. The malicious SVG can be embedded through the SRC attribute of an IMG element, and thus exploitation only requires the victim to visit an attacker-controlled web page.
