Summary

Check the version of ghostscript

Insight

Insight

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): * It was discovered that the ghostscript /invalidaccess checks fail under certain conditions. An attacker could possibly exploit this to bypass the - -dSAFER protection and, for example, execute arbitrary shell commands via a specially crafted PostScript document. (CVE-2018-16509) * ghostscript: LockDistillerParams type confusion (699656) (CVE-2018-15910) * ghostscript: .definemodifiedfont memory corruption if /typecheck is handled (699668) (CVE-2018-16542) * ghostscript: Stack-based out-of-bounds write in pdf_set_text_matrix function in gdevpdts.c (CVE-2018-10194) 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-2018-16509, CVE-2018-15910, and CVE-2018-16542.
