Description

A flaw was found in ghostscript, versions 9.x before 9.50, 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.

Techniques & Countermeasures

  • CWE-863•Incorrect Authorization

    The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check.

  • CWE-648•Incorrect Use of Privileged APIs

    The product does not conform to the API requirements for a function call that requires extra privileges. This could allow attackers to gain privileges by causing the function to be called incorrectly.
