CVE-2025-69204
Description
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to version 7.1.2-12, in the WriteSVGImage function, using an int variable to store number_attributes caused an integer overflow. This, in turn, triggered a buffer overflow and caused a DoS attack. Version 7.1.2-12 fixes the issue.

Mitigations
Immediate action: upgrade to ImageMagick 7.1.2-12.
Interim mitigation if upgrade is delayed:
1. Edit /etc/ImageMagick-7/policy.xml (or ~/.config/ImageMagick/policy.xml):
<policymap>
<policy domain="resource" name="list-length" value="4096"/>
<policy domain="coder" rights="none" pattern="SVG" />
</policymap>2. Restart services that fork ImageMagick (e.g., systemctl restart php-fpm).
3. Test rendering: convert test.svg output.png should reject oversized attribute lists.
Rollback: remove or comment the policy stanza, restart services.
Note: disabling SVG entirely (line 3) is safest if SVG write is non-essential.
