Kerentanan NULL Pointer Dereference pada artifex mupdf. Skor CVSS 3.1 7.5 (High) menurut CISA ADP.

Deskripsi (NVD)

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.
