RHSA-2021:1852 - Moderate: ghostscript security, bug fix, and enhancement update

Synopsis

Moderate: ghostscript security, bug fix, and enhancement update

Type/Severity

Security Advisory Moderate

Topic

An update for ghostscript is now available for Red Hat Enterprise Linux 8.

Red Hat Product Security has rated this update as having a security impact of Moderate. 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.

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.

The following packages have been upgraded to a later upstream version: ghostscript (9.27). (BZ#1874523)

Security Fix(es):

  • ghostscript: use-after-free vulnerability in igc_reloc_struct_ptr() could result in DoS (CVE-2020-14373)

  • ghostscript: buffer overflow in lprn_is_black() in contrib/lips4/gdevlprn.c could result in a DoS (CVE-2020-16287)
