libjbig2dec.a in Artifex jbig2dec 0.13, as used in MuPDF and Ghostscript, has a NULL pointer dereference in the jbig2huffmanget function in jbig2huffman.c. For example, the jbig2dec utility will crash (segmentation fault) when parsing an invalid file.
Artifex Software mupdf v1.24.9 was discovered to contain a segmentation fault via the component /tools/pdfextract.c. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted PDF file.
