CentOS Errata and Security Advisory CESA-2017:1230

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 found that ghostscript did not properly validate the parameters passed to the .rsdparams and .eqproc functions. During its execution, a specially crafted PostScript document could execute code in the context of the ghostscript process, bypassing the -dSAFER protection. (CVE-2017-8291)
