CVE-2024-25117 Information

Description

php-svg-lib is a scalable vector graphics (SVG) file parsing/rendering library. Prior to version 0.5.2 php-svg-lib fails to validate that font-family doesn’t contain a PHAR url which might leads to RCE on PHP < 8.0 and doesn’t validate if external references are allowed. This might leads to bypass of restrictions or RCE on projects that are using it if they do not strictly revalidate the fontName that is passed by php-svg-lib. The Style::fromAttributes() or the Style::parseCssStyle() should check the content of the font-family and prevents it to use a PHAR url to avoid passing an invalid and dangerous fontName value to other libraries. The same check as done in the Style::fromStyleSheets might be reused. Libraries using this library as a dependency might be vulnerable to some bypass of restrictions or even remote code execution if they do not double check the value of the fontName that is passed by php-svg-lib. Version 0.5.2 contains a fix for this issue.
