Description Quality Assurance univentionstaff 2019-09-09 15:45:46 CEST
New Debian ghostscript 9.26a~dfsg-0+deb9u5 fixes:
This update addresses the following issues:
* A flaw was found in, ghostscript versions prior to 9.28, in the  .pdf_hook_DSC_Creator procedure where it did not properly secure its  privileged calls, enabling scripts to bypass `-dSAFER` restrictions. A  specially crafted PostScript file could disable security protection and  then have access to the file system, or execute arbitrary commands.  (CVE-2019-14811)
* ghostscript (CVE-2019-14812)
* A flaw was found in ghostscript, versions 9.x before 9.28, in the  setsystemparams procedure where it did not properly secure its privileged  calls, enabling scripts to bypass `-dSAFER` restrictions. A specially  crafted PostScript file could disable security protection and then have  access to the file system, or execute arbitrary commands. (CVE-2019-14813)
* A flaw was found in, ghostscript versions prior to 9.28, in the  .pdfexectoken and other procedures where it did not properly secure its  privileged calls, enabling scripts to bypass `-dSAFER` restrictions.
