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.

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: Safer mode bypass by .forceput exposure in .pdf_hook_DSC_Creator (701445) (CVE-2019-14811)

  • ghostscript: Safer mode bypass by .forceput exposure in setuserparams (701444) (CVE-2019-14812)

  • ghostscript: Safer mode bypass by .forceput exposure in setsystemparams (701443) (CVE-2019-14813)

  • ghostscript: Safer mode bypass by .forceput exposure in .pdfexectoken and other procedures (701450) (CVE-2019-14817)

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

Note that Tenable Network Security has attempted to extract the preceding description block directly from the corresponding Red Hat security advisory. Virtuozzo provides no description for VZLSA advisories. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
