  <description>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--'
