+ <p>Backport the following fixes from 2.46.x:</p>
+ <p>Librsvg now has limits on the number of loaded XML elements,
+ and the number of referenced elements within an SVG document. This
+ is to mitigate malicious SVGs which try to consume all memory, and
+ those which try to consume an exponential amount of CPU time.</p>
+ <p>Fix stack exhaustion with circular references in <use> elements.</p>
+ <p>Fix a denial-of-service condition from exponential explosion
+ of rendered elements, through nested use of SVG <use> elements in
+ malicious SVGs. This is similar to the XML "billion laughs attack"
+ but for SVG instancing.</p>
