There are 2 open security issues in bookworm.
2 issues left for the package maintainer to handle:
- CVE-2025-46206:
(needs triaging)
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
- CVE-2025-55780:
(needs triaging)
A null pointer dereference occurs in the function break_word_for_overflow_wrap() in MuPDF 1.26.4 when rendering a malformed EPUB document. Specifically, the function calls fz_html_split_flow() to split a FLOW_WORD node, but does not check if node->next is valid before accessing node->next->overflow_wrap, resulting in a crash if the split fails or returns a partial node chain.
You can find information about how to handle these issues in the security team's documentation.
