Summary
A flaw was found in Ghostscript. When processing a specially crafted TrueType font or a document embedding one, an accounting error during font rendering can bypass buffer size checks, triggering a heap-based buffer overflow.
Risk Assessment
A remote attacker could entice a victim or automated service to open the malicious content, potentially resulting in a Denial of Service (DoS) crash or arbitrary code execution.
Recommendation
Update Ghostscript to a patched version and avoid opening untrusted documents or fonts.
Other vulnerabilities in Ghostscript
See all- CVE-2016-7976High
The PS Interpreter in Ghostscript versions 9.18 and 9.20 allows remote attackers to execute arbitrary code via crafted userparams.
- CVE-2016-8602High
The .sethalftone5 function in Ghostscript before version 9.21 allows remote attackers to cause application crashes or potentially execute arbitrary code via a crafted Postscript document that calls .sethalftone5 with an empty operand stack.
- CVE-2016-10317High
The fill_threshhold_buffer function in base/gxht_thresh.c in Ghostscript 9.20 by Artifex Software, Inc. 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.
- CVE-2017-6196High
Multiple use-after-free vulnerabilities in the gx_image_enum_begin function in base/gxipixel.c in Ghostscript before ecceafe3abba2714ef9b432035fe0739d9b1a283 allow remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted PostScript document.
- CVE-2026-39919Critical
Ghostscript before 10.08.0 contains a heap-based buffer overflow in the JPEG 2000 output adapter (base/sjpx_openjpeg.c). An attacker can cause memory corruption by supplying a crafted PDF containing a JPEG 2000 image with mismatched component subsampling factors. The issue is fixed in version 10.08.0.
- CVE-2016-7979Critical
Ghostscript before 9.21 might allow remote attackers to bypass the SAFER mode protection mechanism and consequently execute arbitrary code by leveraging type confusion in .initialize_dsc_parser.
- CVE-2016-7978Critical
A use-after-free vulnerability in Ghostscript 9.20 may allow remote attackers to execute arbitrary code via reference leaks in the .setdevice function.
- CVE-2026-112922Low
Ghostscript has improper bounds validation when processing indexed color values in mesh shading data. A remote attacker can entice a user to process a crafted PDF or PostScript document, triggering an out-of-bounds memory read.
- CVE-2026-112177High
A flaw was found in Ghostscript as shipped with Red Hat Enterprise Linux 8. The correction for CVE-2019-14869 was omitted during the rebase from version 9.25 to 9.27, leaving privileged .forceput operations in the .charkeys procedure insufficiently protected. Processing a specially crafted PostScript file may allow an attacker to bypass -dSAFER restrictions and access files outside the permitted paths or execute commands with the permissions of the Ghostscript process.
- CVE-2026-101258High
A flaw in Ghostscript allows bypassing the -dSAFER sandbox and executing arbitrary shell commands in the context of the Ghostscript process when rendering a crafted PostScript or EPS document. The issue chains memory corruption in document parsing with disabling of internal path access controls at runtime.
