Security update for ghostscript (important)

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–’
