CVE-2026-101258— Ghostscript: ghostscript: -dsafer sandbox bypass via type 5 shading oob write and procedure-stream use-after-free

Quick assessment

Affected
Red Hat Red Hat Enterprise Linux 10
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

发现 Ghostscript 中存在一个安全漏洞。当 Ghostscript 渲染特制的 PostScript 或 EPS 文档时，可能绕过 沙箱限制，并在 Ghostscript 进程的上下文中执行任意 shell 命令。该问题通过将文档解析过程中的内存破坏与运行时禁用内部路径访问控制相结合，形成攻击链。攻击者可以直接交付此类文档，或通过支持将渲染任务委托给 Ghostscript 的格式（例如 EPS 导入或打印转换工作流）间接传递。成功利用该漏洞将损害受 Ghostscript 进程所访问数据的机密性、完整性

Vulnerability Title
Ghostscript: ghostscript: -dsafer sandbox bypass via type 5 shading oob write and procedure-stream use-after-free
Source: CVE Program / CVE List V5
Vulnerability Description
A flaw was found in Ghostscript. When Ghostscript renders a crafted PostScript or EPS document, it can bypass the -dSAFER sandbox and execute arbitrary shell commands in the context of the Ghostscript process. The issue chains memory corruption in document parsing with disabling of internal path access controls at runtime. An attacker can deliver the document directly or through formats that delegate rendering to Ghostscript (for example EPS import or print conversion workflows). Successful exploitation can compromise confidentiality, integrity, and availability of data accessible to the process running Ghostscript.
