3. Description:

The Ghostscript suite contains utilities for rendering PostScript and PDF
documents. Ghostscript translates PostScript code to common bitmap formats
so that the code can be displayed or printed.

Security Fix(es):

* ghostscript: Incorrect free logic in pagedevice replacement (699664)
(CVE-2018-16541)

* ghostscript: Incorrect "restoration of privilege" checking when
running
out of stack during exception handling (CVE-2018-16802)

* ghostscript: User-writable error exception table (CVE-2018-17183)

* ghostscript: Saved execution stacks can leak operator arrays (incomplete
fix for CVE-2018-17183) (CVE-2018-17961)

* ghostscript: Saved execution stacks can leak operator arrays
(CVE-2018-18073)

* ghostscript: 1Policy operator allows a sandbox protection bypass
(CVE-2018-18284)

* ghostscript: Type confusion in setpattern (700141) (CVE-2018-19134)

* ghostscript: Improperly implemented security check in zsetdevice function
in psi/zdevice.c (CVE-2018-19409)

* ghostscript: Uninitialized memory access in the aesdecode operator
(699665) (CVE-2018-15911)

For more details about the security issue(s), including the impact, a CVSS
score, and other related information, refer to the CVE page(s) listed in
the References section.

Red Hat would like to thank Tavis Ormandy (Google Project Zero) for
reporting CVE-2018-16541.

Bug Fix(es):

* It has been found that ghostscript-9.07-31.el7_6.1 introduced regression
during the handling of shading objects, causing a "Dropping incorrect
smooth shading object" warning. With this update, the regression has been
fixed and the described problem no longer occurs. (BZ#1657822)
