An update that fixes 16 vulnerabilities is now available.
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--'
