dvips system() function could allow an attacker to execute commands

dvips-system-execute-commands (10365) The risk level is classified as HighHigh Risk

Description:

dvips could allow a remote attacker to execute commands on the server, caused by a vulnerability in the way it uses the system() function to manage fonts. A remote attacker with print access could create a specially-crafted print job, which would allow the attacker to execute arbitrary commands on the system, once the print job is processed by the system() function.
