Sun Java Runtime Environment font parsing privilege escalation

sun-java-font-privilege-escalation (36061) The risk level is classified as HighHigh Risk

Description:

Sun Java Runtime Environment (JRE) could allow a remote attacker to gain elevated privileges on the system, caused by the improper parsing of fonts in Java applets. By persuading a victim to load a specially-crafted applet, a remote attacker could exploit this vulnerability to read and write local files or to execute local applications on the vulnerable system.
