This update corrects some denial of service issues via exponential element processing, stack exhaustion or application crash when processing specially crafted files, as well as some memory safety issues.

For Debian 9 stretch, these problems have been fixed in version 2.40.21-0+deb9u1.

We recommend that you upgrade your librsvg packages.

For the detailed security status of librsvg please refer to its security tracker page at: [link moved to references]
