pdf_load_obj_stm in pdf/pdf-xref.c in Artifex MuPDF 1.12.0 could reference the object stream recursively and therefore run out of error stack, which allows remote attackers to cause a denial of service via a crafted PDF document.

In ghostscript before version 9.50, the .buildfont1 procedure did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. An attacker could abuse this flaw by creating a specially crafted PostScript file that could escalate privileges and access files outside of restricted areas.

An issue was discovered in Artifex MuJS 1.0.5. The Number#toFixed() and numtostr implementations in jsnumber.c have a stack-based buffer overflow.

An issue was discovered in Artifex MuJS 1.0.5. jscompile.c can cause a denial of service (invalid stack-frame jump) because it lacks an ENDTRY opcode call.

An issue was discovered in Artifex MuJS 1.0.5. It has unlimited recursion because the match function in regexp.c lacks a depth check.

An issue was discovered in Artifex MuJS 1.0.5. regcompx in regexp.c does not restrict regular expression program size, leading to an overflow of the parsed syntax list size.

Artifex MuPDF 1.15.0 has a heap-based buffer overflow in fz_append_display_node located at fitz/list-device.c, allowing remote attackers to execute arbitrary code via a crafted PDF file. This occurs with a large BDC property name that overflows the allocated size of a display list node.

A flaw was found in, ghostscript versions prior to 9.50, in the .pdf_hook_DSC_Creator procedure where it did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. A specially crafted PostScript file could disable security protection and then have access to the file system, or execute arbitrary commands.

A flaw was found in all ghostscript versions 9.x before 9.50, in the .setuserparams2 procedure where it did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. A specially crafted PostScript file could disable security protection and then have access to the file system, or execute arbitrary commands.

A flaw was found in ghostscript, versions 9.x before 9.50, in the setsystemparams procedure where it did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. A specially crafted PostScript file could disable security protection and then have access to the file system, or execute arbitrary commands.

A flaw was found in, ghostscript versions prior to 9.50, in the .pdfexectoken and other procedures where it did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. A specially crafted PostScript file could disable security protection and then have access to the file system, or execute arbitrary commands.

A flaw was found in all versions of ghostscript 9.x before 9.50, where the `.charkeys` procedure, where it did not properly secure its privileged calls, enabling scripts to bypass `-dSAFER` restrictions. An attacker could abuse this flaw by creating a specially crafted PostScript file that could escalate privileges within the Ghostscript and access files outside of restricted areas or execute commands.

Artifex MuPDF before 1.16.0 has a heap-based buffer over-read in fz_chartorune in fitz/string.c because pdf/pdf-op-filter.c does not check for a missing string.

Artifex Ghostscript through 9.26 mishandles .completefont. NOTE: this issue exists because of an incomplete fix for CVE-2019-3839.

It was found that the superexec operator was available in the internal dictionary in ghostscript before 9.27. A specially crafted PostScript file could use this flaw in order to, for example, have access to the file system outside of the constrains imposed by -dSAFER.

It was found that the forceput operator could be extracted from the DefineResource method in ghostscript before 9.27. A specially crafted PostScript file could use this flaw in order to, for example, have access to the file system outside of the constrains imposed by -dSAFER.

It was found that in ghostscript some privileged operators remained accessible from various places after the CVE-2019-6116 fix. A specially crafted PostScript file could use this flaw in order to, for example, have access to the file system outside of the constrains imposed by -dSAFER. Ghostscript versions before 9.27 are vulnerable.

In Artifex Ghostscript through 9.26, ephemeral or transient procedures can allow access to system operators, leading to remote code execution.

Artifex MuPDF 1.14.0 has a SEGV in the function fz_load_page of the fitz/document.c file, as demonstrated by mutool. This is related to page-number mishandling in cbz/mucbz.c, cbz/muimg.c, and svg/svg-doc.c.

svg-run.c in Artifex MuPDF 1.14.0 has infinite recursion with stack consumption in svg_run_use_symbol, svg_run_element, and svg_run_use, as demonstrated by mutool.

Usage of an uninitialized variable in the function fz_load_jpeg in Artifex MuPDF 1.14 can result in a heap overflow vulnerability that allows an attacker to execute arbitrary code.

jbig2_image_compose in jbig2_image.c in Artifex jbig2dec before 0.18 has a heap-based buffer overflow.

A use after free was found in igc_reloc_struct_ptr() of psi/igc.c of ghostscript-9.25. A local attacker could supply a specially crafted PDF file to cause a denial of service.

A memory corruption issue was found in Artifex Ghostscript 9.50 and 9.52. Use of a non-standard PostScript operator can allow overriding of file access controls. The 'rsearch' calculation for the 'post' size resulted in a size that was too large, and could underflow to max uint32_t. This was fixed in commit 5d499272b95a6b890a1397e11d20937de000d31b.

A buffer overflow vulnerability in lprn_is_black() in contrib/lips4/gdevlprn.c of Artifex Software GhostScript v9.50 allows a remote attacker to cause a denial of service via a crafted PDF file. This is fixed in v9.51.

A buffer overflow vulnerability in pj_common_print_page() in devices/gdevpjet.c of Artifex Software GhostScript v9.50 allows a remote attacker to cause a denial of service via a crafted PDF file. This is fixed in v9.51.

A buffer overflow vulnerability in cif_print_page() in devices/gdevcif.c of Artifex Software GhostScript v9.50 allows a remote attacker to cause a denial of service via a crafted PDF file. This is fixed in v9.51.

A buffer overflow vulnerability in jetp3852_print_page() in devices/gdev3852.c of Artifex Software GhostScript v9.50 allows a remote attacker to cause a denial of service via a crafted PDF file. This is fixed in v9.51.

A buffer overflow vulnerability in contrib/gdevdj9.c of Artifex Software GhostScript v9.50 allows a remote attacker to cause a denial of service via a crafted PDF file. This is fixed in v9.51.

A buffer overflow vulnerability in mj_raster_cmd() in contrib/japanese/gdevmjc.c of Artifex Software GhostScript v9.50 allows a remote attacker to cause a denial of service via a crafted PDF file. This is fixed in v9.51.

A null pointer dereference vulnerability in compose_group_nonknockout_nonblend_isolated_allmask_common() in base/gxblend.c of Artifex Software GhostScript v9.50 allows a remote attacker to cause a denial of service via a crafted PDF file. This is fixed in v9.51.

A buffer overflow vulnerability in epsc_print_page() in devices/gdevepsc.c of Artifex Software GhostScript v9.50 allows a remote attacker to cause a denial of service via a crafted PDF file. This is fixed in v9.51.

A null pointer dereference vulnerability in clj_media_size() in devices/gdevclj.c of Artifex Software GhostScript v9.50 allows a remote attacker to cause a denial of service via a crafted PDF file. This is fixed in v9.51.

A buffer overflow vulnerability in GetNumWrongData() in contrib/lips4/gdevlips.c of Artifex Software GhostScript from v9.18 to v9.50 allows a remote attacker to cause a denial of service via a crafted PDF file. This is fixed in v9.51.

A buffer overflow vulnerability in FloydSteinbergDitheringC() in contrib/gdevbjca.c of Artifex Software GhostScript v9.50 allows a remote attacker to cause a denial of service via a crafted PDF file. This is fixed in v9.51.
