"This update for ghostscript-library fixes the following issues :

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

CVE-2018-16540: Attackers able to supply crafted PostScript files to
the builtin PDF14 converter could use a use-after-free in copydevice
handling to crash the interpreter or possibly have unspecified other
impact. (bsc#1107420)

CVE-2018-16541: Attackers able to supply crafted PostScript files
could use incorrect free logic in pagedevice replacement to crash the
interpreter. (bsc#1107421)

CVE-2018-16542: Attackers able to supply crafted PostScript files
could use insufficient interpreter stack-size checking during error
handling to crash the interpreter. (bsc#1107413)

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

CVE-2018-16513: Attackers able to supply crafted PostScript files
could use a type confusion in the setcolor function to crash the
interpreter or possibly have unspecified other impact. (bsc#1107412)

CVE-2018-15910: Attackers able to supply crafted PostScript files
could use a type confusion in the LockDistillerParams parameter to
crash the interpreter or execute code. (bsc#1106173)

CVE-2017-9611: The Ins_MIRP function allowed remote attackers to cause
a denial of service (heap-based buffer over-read and application
crash) or possibly have unspecified other impact via a crafted
document. (bsc#1050893)

description block directly from the SUSE security advisory. Tenable
