The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has ghostscript packages installed that are affected by multiple vulnerabilities:

  - An issue was discovered in Artifex Ghostscript before     9.26. LockSafetyParams is not checked correctly if     another device is used. (CVE-2018-19409)

  - It was discovered that the ghostscript .tempfile     function did not properly handle file permissions. An     attacker could possibly exploit this to exploit this to     bypass the -dSAFER protection and delete files or     disclose their content via a specially crafted     PostScript document. (CVE-2018-15908)

  - An issue was discovered in Artifex Ghostscript before     9.25. Incorrect restoration of privilege checking when     running out of stack during exception handling could be     used by attackers able to supply crafted PostScript to     execute code using the pipe instruction. This is due     to an incomplete fix for CVE-2018-16509.
    (CVE-2018-16802)

  - It was discovered that the ghostscript device cleanup     did not properly handle devices replaced with a null     device. An attacker could possibly exploit this to     bypass the -dSAFER protection and crash ghostscript or,     possibly, execute arbitrary code in the ghostscript     context via a specially crafted PostScript document.
    (CVE-2018-16541)

  - It was discovered that ghostscript did not properly     verify the key used in aesdecode. An attacker could     possibly exploit this to bypass the -dSAFER protection     and crash ghostscript or, possibly, execute arbitrary     code in the ghostscript context via a specially crafted     PostScript document. (CVE-2018-15911)

  - It was discovered that the ghostscript did not properly     restrict access to files open prior to enabling the
    -dSAFER mode. An attacker could possibly exploit this to     bypass the -dSAFER protection and disclose the content     of affected files via a specially crafted PostScript     document. (CVE-2018-16539)

  - Artifex Ghostscript before 9.25 allowed a user-writable     error exception table, which could be used by remote     attackers able to supply crafted PostScript to     potentially overwrite or replace error handlers to     inject code. (CVE-2018-17183)

  - Artifex Ghostscript 9.25 and earlier allows attackers to     bypass a sandbox protection mechanism via vectors     involving errorhandler setup. NOTE: this issue exists     because of an incomplete fix for CVE-2018-17183.
    (CVE-2018-17961)

  - Artifex Ghostscript allows attackers to bypass a sandbox     protection mechanism by leveraging exposure of system     operators in the saved execution stack in an error     object. (CVE-2018-18073)

  - Artifex Ghostscript 9.25 and earlier allows attackers to     bypass a sandbox protection mechanism via vectors     involving the 1Policy operator. (CVE-2018-18284)

  - It was found that RHSA-2018:2918 did not fully fix     CVE-2018-16509. An attacker could possibly exploit     another variant of the flaw and bypass the -dSAFER     protection to, for example, execute arbitrary shell     commands via a specially crafted PostScript document.
    (CVE-2018-16863)

  - In Artifex Ghostscript through 9.25, the setpattern     operator did not properly validate certain types. A     specially crafted PostScript document could exploit this     to crash Ghostscript or, possibly, execute arbitrary     code in the context of the Ghostscript process. This is     a type confusion issue because of failure to check     whether the Implementation of a pattern dictionary was a     structure type. (CVE-2018-19134)

  - It was discovered that the ghostscript .shfill operator     did not properly validate certain types. An attacker     could possibly exploit this to bypass the -dSAFER     protection and crash ghostscript or, possibly, execute     arbitrary code in the ghostscript context via a     specially crafted PostScript document. (CVE-2018-15909)

  - It was discovered that the ghostscript .type operator     did not properly validate its operands. A specially     crafted PostScript document could exploit this to crash     ghostscript or, possibly, execute arbitrary code in the     context of the ghostscript process. (CVE-2018-16511)

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

The version of ghostscript installed on the remote host is prior to 9.25-5. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2021-1598 advisory.

    Artifex Ghostscript before 9.25 allowed a user-writable error exception table, which could be used by     remote attackers able to supply crafted PostScript to potentially overwrite or replace error handlers to     inject code. (CVE-2018-17183)

    Artifex Ghostscript 9.25 and earlier allows attackers to bypass a sandbox protection mechanism via vectors     involving errorhandler setup. NOTE: this issue exists because of an incomplete fix forCVE-2018-17183.
    (CVE-2018-17961)

    Artifex Ghostscript allows attackers to bypass a sandbox protection mechanism by leveraging exposure of     system operators in the saved execution stack in an error object. (CVE-2018-18073)

    Artifex Ghostscript 9.25 and earlier allows attackers to bypass a sandbox protection mechanism via vectors     involving the 1Policy operator. (CVE-2018-18284)

    In Artifex Ghostscript through 9.25, the setpattern operator did not properly validate certain types. A     specially crafted PostScript document could exploit this to crash Ghostscript or, possibly, execute     arbitrary code in the context of the Ghostscript process. This is a type confusion issue because of     failure to check whether the Implementation of a pattern dictionary was a structure type. (CVE-2018-19134)

    An issue was discovered in Artifex Ghostscript before 9.26. LockSafetyParams is not checked correctly if     another device is used. (CVE-2018-19409)

    psi/zdevice2.c in Artifex Ghostscript before 9.26 allows remote attackers to bypass intended access     restrictions because available stack space is not checked when the device remains the same.
    (CVE-2018-19475)

    psi/zicc.c in Artifex Ghostscript before 9.26 allows remote attackers to bypass intended access     restrictions because of a setcolorspace type confusion. (CVE-2018-19476)

    psi/zfjbig2.c in Artifex Ghostscript before 9.26 allows remote attackers to bypass intended access     restrictions because of a JBIG2Decode type confusion. (CVE-2018-19477)

    A flaw was found in the .pdf_hook_DSC_Creator procedure where it did not properly secure its privileged     calls, enabling scripts to bypass `-dSAFER` restrictions. A specially crafted PostScript file could     disable security protection and then have access to the file system, or execute arbitrary commands.
    (CVE-2019-14811)

    A flaw was found in the .setuserparams2 procedure where it did not properly secure its privileged calls,     enabling scripts to bypass `-dSAFER` restrictions. A specially crafted PostScript file could disable     security protection and then have access to the file system, or execute arbitrary commands.
    (CVE-2019-14812)

    A flaw was found in the setsystemparams procedure where it did not properly secure its privileged calls,     enabling scripts to bypass `-dSAFER` restrictions. A specially crafted PostScript file could disable     security protection and then have access to the file system, or execute arbitrary commands.
    (CVE-2019-14813)

    A flaw was found in the .pdfexectoken and other procedures where it did not properly secure its privileged     calls, enabling scripts to bypass `-dSAFER` restrictions. A specially crafted PostScript file could     disable security protection and then have access to the file system, or execute arbitrary commands.
    (CVE-2019-14817)

    A flaw was found in the `.charkeys` procedure, where it did not properly secure its privileged calls,     enabling scripts to bypass `-dSAFER` restrictions. An attacker could abuse this flaw by creating a     specially crafted PostScript file that could escalate privileges within the Ghostscript and access files     outside of restricted areas or execute commands. (CVE-2019-14869)

    It was found that the superexec operator was available in the internal dictionary.  A specially crafted     PostScript file could use this flaw in order to, for example, have access to the file system outside of     the constrains imposed by -dSAFER. (CVE-2019-3835)

    It was found that the forceput operator could be extracted from the DefineResource method. A specially     crafted PostScript file could use this flaw in order to, for example, have access to the file system     outside of the constrains imposed by -dSAFER. (CVE-2019-3838)

    It was found that some privileged operators remained accessible from various places after     theCVE-2019-6116fix. A specially crafted PostScript file could use this flaw in order to, for example,     have access to the file system outside of the constrains imposed by -dSAFER. (CVE-2019-3839)

    It was found that ghostscript could leak sensitive operators on the operand stack when a pseudo-operator     pushes a subroutine. A specially crafted PostScript file could use this flaw to escape the -dSAFER     protection in order to, for example, have access to the file system outside of the SAFER constraints.

  - CVE-2018-15909: Prevent type confusion using the .shfill     operator that could have been used by attackers able to     supply crafted PostScript files to crash the interpreter     or potentially execute code (bsc#1106172).

  - CVE-2018-15908: Prevent attackers that are able to     supply malicious PostScript files to bypass .tempfile     restrictions and write files (bsc#1106171).

  - CVE-2018-15910: Prevent a type confusion in the     LockDistillerParams parameter that could have been used     to crash the interpreter or execute code (bsc#1106173).

  - CVE-2018-15911: Prevent use uninitialized memory access     in the aesdecode operator that could have been used to     crash the interpreter or potentially execute code     (bsc#1106195).

  - CVE-2018-16513: Prevent a type confusion in the setcolor     function that could have been used to crash the     interpreter or possibly have unspecified other impact     (bsc#1107412).

  - CVE-2018-16509: Incorrect 'restoration of privilege'     checking during handling of /invalidaccess exceptions     could be have been used by attackers able to supply     crafted PostScript to execute code using the 'pipe'     instruction (bsc#1107410).

  - CVE-2018-16510: Incorrect exec stack handling in the     'CS' and 'SC' PDF primitives could have been used by     remote attackers able to supply crafted PDFs to crash     the interpreter or possibly have unspecified other     impact (bsc#1107411).

  - CVE-2018-16542: Prevent attackers able to supply crafted     PostScript files from using insufficient interpreter     stack-size checking during error handling to crash the     interpreter (bsc#1107413).

  - CVE-2018-16541: Prevent attackers able to supply crafted     PostScript files from using incorrect free logic in     pagedevice replacement to crash the interpreter     (bsc#1107421).

  - CVE-2018-16540: Prevent use-after-free in copydevice     handling that could have been used to crash the     interpreter or possibly have unspecified other impact     (bsc#1107420).

  - CVE-2018-16539: Prevent attackers able to supply crafted     PostScript files from using incorrect access checking in     temp file handling to disclose contents of files on the     system otherwise not readable (bsc#1107422).

  - CVE-2018-16543: gssetresolution and gsgetresolution     allowed attackers to have an unspecified impact     (bsc#1107423).

  - CVE-2018-16511: A type confusion in 'ztype' could have     been used by remote attackers able to supply crafted     PostScript to crash the interpreter or possibly have     unspecified other impact (bsc#1107426).

  - CVE-2018-16585: The .setdistillerkeys PostScript command     was accepted even though it is not intended for use     during document processing (e.g., after the startup     phase). This lead to memory corruption, allowing remote     attackers able to supply crafted PostScript to crash the     interpreter or possibly have unspecified other impact     (bsc#1107581).

  - CVE-2018-16802: Incorrect 'restoration of privilege'     checking when running out of stack during exception     handling could have been used by attackers able to     supply crafted PostScript to execute code using the     'pipe' instruction. This is due to an incomplete fix for     CVE-2018-16509 (bsc#1108027).

These non-security issues were fixed :

  - Fixes problems with argument handling, some unintended     results of the security fixes to the SAFER file access     restrictions (specifically accessing ICC profile files).

  - Avoid that ps2epsi fails with 'Error: /undefined in
    --setpagedevice--'
