Published: 2018-09-06
Updated: 2024-08-05

Summary

An issue was discovered in Artifex Ghostscript before 9.24. The .setdistillerkeys PostScript command is accepted even though it is not intended for use during document processing (e.g., after the startup phase). This leads to memory corruption, allowing remote attackers able to supply crafted PostScript to crash the interpreter or possibly have unspecified other impact. Note: A reputable source believes that the CVE is potentially a duplicate of CVE-2018-15910 as explained in Red Hat bugzilla (https://bugzilla.redhat.com/show_bug.cgi?id=1626193)

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

"This update for ghostscript to version 9.25 fixes the following 
issues :

These security issues were fixed :

  - CVE-2018-17183: Remote attackers were be able to supply
    crafted PostScript to potentially overwrite or replace
    error handlers to inject code (bsc#1109105)

  - 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--'

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).

The update package also includes non-security fixes. See advisory for
details.

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
