In Artifex MuPDF 1.12.0, there is a heap-based buffer overflow vulnerability in the do_pdf_save_document function in the pdf/pdf-write.c file. Remote attackers could leverage the vulnerability to cause a denial of service via a crafted pdf file.

Heap-based buffer overflow in the ensure_solid_xref function in pdf/pdf-xref.c in Artifex MuPDF 1.12.0 allows a remote attacker to potentially execute arbitrary code via a crafted PDF file, because xref subsection object numbers are unrestricted.

In MuPDF 1.12.0, there is an infinite loop vulnerability and application hang in the pdf_parse_array function (pdf/pdf-parse.c) because EOF is not considered. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted pdf file.

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

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.

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 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.

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.

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.
