CVE-2025-46206: n/a
An issue in Artifex mupdf 1.25.6, 1.25.5 allows a remote attacker to cause a denial of service via an infinite recursion in the `mutool clean` utility. When processing a crafted PDF file containing cyclic /Next references in the outline structure, the `strip_outline()` function enters infinite recursion
AI Analysis
Technical Summary
CVE-2025-46206 is a denial of service vulnerability in Artifex mupdf versions 1.25.5 and 1.25.6. The mutool clean utility's strip_outline() function can enter infinite recursion when handling a specially crafted PDF file containing cyclic /Next references in its outline structure. This infinite recursion results in a denial of service by exhausting resources and crashing the application. No known exploits are reported in the wild, and no patch or official fix has been indicated in the provided data.
Potential Impact
Successful exploitation causes a denial of service condition by triggering infinite recursion in the mutool clean utility, leading to application crash or resource exhaustion. There is no impact on confidentiality or integrity reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, avoid processing untrusted or suspicious PDF files with mutool clean. Monitor vendor channels for updates regarding an official fix.
