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.

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.

An issue was discovered in Artifex Software, Inc. MuJS before 8f62ea10a0af68e56d5c00720523ebcba13c2e6a. The MakeDay function in jsdate.c does not validate the month, leading to an integer overflow when parsing a specially crafted JS file.

An issue was discovered in Artifex Software, Inc. MuJS before 4006739a28367c708dea19aeb19b8a1a9326ce08. The jsR_setproperty function in jsrun.c lacks a check for a negative array length. This leads to an integer overflow in the js_pushstring function in jsrun.c when parsing a specially crafted JS file.

pdf/pdf-write.c in Artifex MuPDF before 1.12.0 mishandles certain length changes when a repair operation occurs during a clean operation, which allows remote attackers to cause a denial of service (buffer overflow and application crash) or possibly have unspecified other impact via a crafted PDF document.

regexp.c in Artifex Software, Inc. MuJS allows attackers to cause a denial of service (NULL pointer dereference and crash) via vectors related to regular expression compilation.

ghostscript: Heap-buffer over-read in the gs_alloc_ref_array function

The gs_alloc_ref_array function in psi/ialloc.c in Artifex Ghostscript 9.21 allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted PostScript document. This is related to a lack of an integer overflow check in base/gsalloc.c.

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 GSView 6.0 Beta on Windows allows attackers to execute arbitrary code or cause a denial of service via a crafted .xps file, related to a "Read Access Violation on Block Data Move starting at mupdfnet64!mIncrementalSaveFile+0x0000000000193359."

Artifex GSView 6.0 Beta on Windows allows attackers to cause a denial of service or possibly have unspecified other impact via a crafted .pdf file, related to "Data from Faulting Address controls Branch Selection starting at mupdfnet64!mIncrementalSaveFile+0x000000000000344e."

Artifex GSView 6.0 Beta on Windows allows attackers to cause a denial of service or possibly have unspecified other impact via a crafted .pdf file, related to "Possible Stack Corruption starting at KERNELBASE!RaiseException+0x0000000000000068."

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.

ghostscript: Heap-buffer overflow in the fill_threshold_buffer function

The fill_threshhold_buffer function in base/gxht_thresh.c in Artifex Software, Inc. Ghostscript 9.20 allows remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted PostScript 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.

ghostscript: Out of bounds read in igc_reloc_struct_ptr()

psi/ztoken.c in Artifex Ghostscript 9.21 mishandles references to the scanner state structure, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted PostScript document, related to an out-of-bounds read in the igc_reloc_struct_ptr function in psi/igc.c.

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.

ghostscript: Heap-buffer over-read in the Ins_JMPR function

The Ins_JMPR function in base/ttinterp.c in Artifex Ghostscript GhostXPS 9.21 allows remote attackers to cause a denial of service (heap-based buffer over-read and application crash) or possibly have unspecified other impact via a crafted document.
