A trivial sandbox (enabled with the `-dSAFER` option) escape flaw was found in the ghostscript interpreter by injecting a specially crafted pipe command. This flaw allows a specially crafted document to execute arbitrary commands on the system in the context of the ghostscript interpreter. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - A trivial sandbox (enabled with the `-dSAFER` option) escape flaw was found in the ghostscript interpreter
    by injecting a specially crafted pipe command. This flaw allows a specially crafted document to execute
    arbitrary commands on the system in the context of the ghostscript interpreter. The highest threat from
    this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2021-3781)

The remote CentOS Linux 9 host has packages installed that are affected by a vulnerability as referenced in the ghostscript-9.54.0-4.el9 build changelog.

  - A trivial sandbox (enabled with the `-dSAFER` option) escape flaw was found in the ghostscript interpreter     by injecting a specially crafted pipe command. This flaw allows a specially crafted document to execute     arbitrary commands on the system in the context of the ghostscript interpreter. The highest threat from     this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2021-3781)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote host is affected by the vulnerability described in GLSA-202211-11 (GPL Ghostscript: Multiple Vulnerabilities)

  - A trivial sandbox (enabled with the `-dSAFER` option) escape flaw was found in the ghostscript interpreter     by injecting a specially crafted pipe command. This flaw allows a specially crafted document to execute     arbitrary commands on the system in the context of the ghostscript interpreter. The highest threat from     this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2021-3781)

  - A NULL pointer dereference vulnerability was found in Ghostscript, which occurs when it tries to render a     large number of bits in memory. When allocating a buffer device, it relies on an init_device_procs defined     for the device that uses it as a prototype that depends upon the number of bits per pixel. For bpp > 64,     mem_x_device is used and does not have an init_device_procs defined. This flaw allows an attacker to parse     a large number of bits (more than 64 bits per pixel), which triggers a NULL pointer dereference flaw,     causing an application to crash. (CVE-2022-2085)

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

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

The remote Debian 11 host has packages installed that are affected by a vulnerability as referenced in the dsa-4972 advisory.

    It was discovered that Ghostscript, the GPL PostScript/PDF interpreter, does not properly validate access     for the %pipe%, %handle% and %printer% io devices, which could result in the execution of arbitrary     code if a malformed Postscript file is processed (despite the -dSAFER sandbox being enabled). For the     stable distribution (bullseye), this problem has been fixed in version 9.53.3~dfsg-7+deb11u1. We recommend     that you upgrade your ghostscript packages. For the detailed security status of ghostscript please refer     to its security tracker page at: https://security-tracker.debian.org/tracker/ghostscript

The remote Ubuntu 20.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-5075-1 advisory.

    It was discovered that Ghostscript incorrectly handled certain PostScript files. If a user or automated     system were tricked into processing a specially crafted file, a remote attacker could possibly use this     issue to access arbitrary files, execute arbitrary code, or cause a denial of service.

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