Detail
Problem Description: An update for ghostscript is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Client (v. 7) - x86_64 Red Hat Enterprise Linux Client Optional (v. 7) - noarch, x86_64 Red Hat Enterprise Linux ComputeNode (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode Optional (v. 7) - noarch, x86_64 Red Hat Enterprise Linux Server (v. 7) - ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 7) - noarch, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - x86_64 Red Hat Enterprise Linux Workstation Optional (v. 7) - noarch, x86_64 Red Hat Enterprise Linux for ARM and IBM Power LE (POWER9) Server (v. 7) - aarch64, ppc64le, s390x Red Hat Enterprise Linux for ARM and IBM Power LE (POWER9) Server Optional (v. 7) - aarch64, noarch, ppc64le, s390x 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) 4.
