An integer overflow was discovered in pdf_read_new_xref_section in pdf/pdf-xref.c in Artifex MuPDF 1.11.

The build_filter_chain function in pdf/pdf-stream.c in Artifex MuPDF before 2017-09-25 mishandles a certain case where a variable may reside in a register, which allows remote attackers to cause a denial of service (Fitz fz_drop_imp use-after-free and application crash) or possibly have unspecified other impact via a crafted PDF document.

Artifex MuPDF 1.11 allows attackers to cause a denial of service or possibly have unspecified other impact via a crafted .xps file, related to "Data from Faulting Address controls Branch Selection starting at mupdf+0x000000000016aa61" on Windows. This occurs because xps_load_links_in_glyphs in xps/xps-link.c does not verify that an xps font could be loaded.

Artifex MuPDF 1.11 allows attackers to cause a denial of service or possibly have unspecified other impact via a crafted .xps file, related to "Data from Faulting Address controls Branch Selection starting at mupdf+0x000000000016cb4f" on Windows. This occurs because of mishandling of XML tag name comparisons.

Artifex MuPDF 1.11 allows attackers to execute arbitrary code or cause a denial of service via a crafted .xps file, related to a "User Mode Write AV near NULL starting at wow64!Wow64NotifyDebugger+0x000000000000001d" on Windows. This occurs because read_zip_dir_imp in fitz/unzip.c does not check whether size fields in a ZIP entry are negative numbers.

The count_entries function in pdf-layer.c in Artifex Software, Inc. MuPDF 1.10a allows remote attackers to cause a denial of service (stack consumption and application crash) via a crafted PDF document.

Use-after-free vulnerability in the fz_subsample_pixmap function in fitz/pixmap.c in Artifex MuPDF 1.10a allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted document.

Buffer overflow in the my_getline function in jstest_main.c in Mujstest in Artifex Software, Inc. MuPDF before 1.10 allows remote attackers to cause a denial of service (out-of-bounds write) via a crafted file.

Buffer overflow in the main function in jstest_main.c in Mujstest in Artifex Software, Inc. MuPDF before 1.10 allows remote attackers to cause a denial of service (out-of-bounds write) via a crafted file.

Stack-based buffer overflow in jstest_main.c in mujstest in Artifex Software, Inc. MuPDF 1.10a allows remote attackers to have unspecified impact via a crafted image.

The pdf_to_num function in pdf-object.c in MuPDF before 1.10 allows remote attackers to cause a denial of service (use-after-free and application crash) via a crafted file.

Heap-based buffer overflow in the fz_subsample_pixmap function in fitz/pixmap.c in MuPDF 1.10a allows remote attackers to cause a denial of service (out-of-bounds read and crash) via a crafted image.

An issue was discovered in Artifex MuPDF before 1912de5f08e90af1d9d0a9791f58ba3afdb9d465. The pdf_run_xobject function in pdf-op-run.c encounters a NULL pointer dereference during a Fitz fz_paint_pixmap_with_mask painting operation. Versions 1.11 and later are unaffected.

Use-after-free vulnerability in the pdf_load_xref function in pdf/pdf-xref.c in MuPDF allows remote attackers to cause a denial of service (crash) via a crafted PDF file.

Heap-based buffer overflow in the pdf_load_mesh_params function in pdf/pdf-shade.c in MuPDF allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a large decode array.

Stack-based buffer overflow in the xps_parse_color function in xps/xps-common.c in MuPDF 1.3 and earlier allows remote attackers to execute arbitrary code via a large number of entries in the ContextColor value of the Fill attribute in a Path element.

Stack-based buffer overflow in the pdfmoz_onmouse function in apps/mozilla/moz_main.c in the MuPDF plug-in 2008.09.02 for Firefox allows remote attackers to execute arbitrary code via a crafted web site.
