Denial Of Service (DoS)

phenx/php-svg-lib is vulnerable to Denial Of Service (DoS). The vulnerability is caused due to a missing validation for circular references reached while parsing the attributes passed to a use tag inside an SVG document. An attacker can craft a malicious SVG file and send multiple request to a system to render the same SVG file that can potentially cause resource exhaustion to the point that the system is unable to handle incoming request leading to Denial Of Service (DoS).
