Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, the ps coders, responsible for writing PostScript files, fails to sanitize the input before writing it into the PostScript header. An attacker can provide a malicous file and inject arbitrary PostScript code. When the resulting file is processed by a printer or a viewer (like Ghostscript), the injected code is interpreted and executed. The html encoder does not properly escape strings that are written to in the html document. An attacker can provide a malicious file and injection arbitrary html code. Versions 7.1.2-15 and 6.9.13-40 contain a patch. (CVE-2026-25797)
