DescriptionThe vulnerability allows a remote attacker to bypass the sandbox protection mechanism on the target system.
The vulnerability exists due to the failure of the sandbox protection mechanism of the affected software when the 1Policy operator is used. A remote unauthenticated attacker can trick the victim into accessing a PostScript file that submits malicious input, bypass the sandbox protection mechanism and modify or replace error handlers used by the software, which the attacker could use to inject and execute arbitrary code on the system.
MitigationInstall update from vendor's website.
