MuPDF 1.23.0 through 1.27.0 Barcode Decoding Double Free

MuPDF versions 1.23.0 through 1.27.0 contain a double-free vulnerability in fz_fill_pixmap_from_display_list() when an exception occurs during display list rendering. The function accepts a caller-owned fz_pixmap pointer but incorrectly drops the pixmap in its error handling path before rethrowing the exception. Callers (including the barcode decoding path in fz_decode_barcode_from_display_list) also drop the same pixmap in cleanup, resulting in a double-free that can corrupt the heap and crash the process. This issue affects applications that enable and use MuPDF barcode decoding and can be triggered by processing crafted input that causes a rendering-time error while decoding barcodes.

ghostscript: corruption of operand stack

Artifex Ghostscript through 2017-04-26 allows -dSAFER bypass and remote command execution via .rsdparams type confusion with a "/OutputFile (%pipe%" substring in a crafted .eps document that is an input to the gs program, as exploited in the wild in April 2017.

CVE-2026-3308

An integer overflow vulnerability in 'pdf-image.c' in Artifex's MuPDF version 1.27.0 allows an attacker to maliciously craft a PDF that can trigger an integer overflow within the 'pdf_load_image_imp' function. This allows a heap out-of-bounds write that could be exploited for arbitrary code execution.

In Artifex GhostXPS before 10.06.0, there is a stack-based buffer overflow in xps_unpredict_tiff in xpstiff.c because the samplesperpixel value is not checked.

Artifex MuPDF win_main.c get_system_dpi uncontrolled search path

A flaw has been found in Artifex MuPDF up to 1.26.1 on Windows. The impacted element is the function get_system_dpi of the file platform/x11/win_main.c. This manipulation causes uncontrolled search path. The attack requires local access. The attack is considered to have high complexity. The exploitability is regarded as difficult. Upgrading to version 1.26.2 is sufficient to resolve this issue. Patch name: ebb125334eb007d64e579204af3c264aadf2e244. Upgrading the affected component is recommended.

Artifex GhostPDL New Output File Open Error gdevpdf.c pdf_ferror null pointer dereference

A vulnerability was found in Artifex GhostPDL up to 3989415a5b8e99b9d1b87cc9902bde9b7cdea145. It has been classified as problematic. This affects the function pdf_ferror of the file devices/vector/gdevpdf.c of the component New Output File Open Error Handler. The manipulation leads to null pointer dereference. It is possible to initiate the attack remotely. The identifier of the patch is 619a106ba4c4abed95110f84d5efcd7aee38c7cb. It is recommended to apply a patch to fix this issue.

CVE-2026-3029

A path traversal and arbitrary file write vulnerability exist in the embedded get function in '_main_.py' in PyMuPDF version, 1.26.5.

libjpeg: information leak (read of uninitialized memory)

The get_sos function in jdmarker.c in (1) libjpeg 6b and (2) libjpeg-turbo through 1.3.0, as used in Google Chrome before 31.0.1650.48, Ghostscript, and other products, does not check for certain duplications of component data during the reading of segments that follow Start Of Scan (SOS) JPEG markers, which allows remote attackers to obtain sensitive information from uninitialized memory locations via a crafted JPEG image.

freeglut: memory leak via glutAddMenuEntry() function

freeglut through 3.4.0 was discovered to contain a memory leak via the menuEntry variable in the glutAddMenuEntry function.

freeglut: memory leak via glutAddSubMenu() function

freeglut 3.4.0 was discovered to contain a memory leak via the menuEntry variable in the glutAddSubMenu function.

ghostscript: Out-of-Bounds Data Access in Ghostscript Leads to Arbitrary Code Execution

An issue was discovered in psi/zfile.c in Artifex Ghostscript before 10.04.0. Out-of-bounds data access in filenameforall can lead to arbitrary code execution.

ghostscript: Out-of-Bounds Read in Ghostscript Indexed Color Space

An issue was discovered in psi/zcolor.c in Artifex Ghostscript before 10.04.0. There is an out-of-bounds read when reading color in Indexed color space.

ghostscript: Path Traversal and Code Execution via Integer Overflow in Ghostscript

An issue was discovered in base/gsdevice.c in Artifex Ghostscript before 10.04.0. An integer overflow when parsing the filename format string (for the output filename) results in path truncation, and possible path traversal and code execution.

ghostscript: Arbitrary Code Execution in Artifex Ghostscript Pattern Color Space

An issue was discovered in psi/zcolor.c in Artifex Ghostscript before 10.04.0. An unchecked Implementation pointer in Pattern color space could lead to arbitrary code execution.
