Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Librsvg versions before 2.57.5, from 2.57.90 before 2.60.3, from 2.61.0 before 2.61.5, from 2.61.90 before 2.62.4, and from 2.62.90 before 2.63.2 are vulnerable. An attacker who can supply an SVG document to be parsed can trigger a use-after-free through nested XInclude entries with duplicate entity names, which may allow code execution. Upgrade to 2.57.5, 2.60.3, 2.61.5, 2.62.4, 2.63.2, or a later release in the matching series.
