"According to the versions of the ghostscript packages installed, the EulerOS installation on the remote host is affected
by the following vulnerabilities :

    Artifex Ghostscript before 10.03.1 allows memory corruption, and SAFER sandbox bypass, via format string
    injection with a uniprint device.(CVE-2024-29510)

    An issue was discovered in Artifex Ghostscript before 10.03.1. Path traversal and command execution can
    occur (via a crafted PostScript document) because of path reduction in base/gpmisc.c. For example,
    restrictions on use of %pipe% can be bypassed via the aa/../%pipe%command# output
    filename.(CVE-2024-33869)

    An issue was discovered in Artifex Ghostscript before 10.03.1. There is path traversal (via a crafted
    PostScript document) to arbitrary files if the current directory is in the permitted paths. For example,
    there can be a transformation of ../../foo to ./../../foo and this will grant access if ./ is
    permitted.(CVE-2024-33870)

Tenable has extracted the preceding description block directly from the EulerOS ghostscript security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
