 |
|
| I've read that a java-enabled browser is a security risk even on Linux. How can I be sure I'm not vulnerable? |

Depends on your browser. Firefox uses java as a plugin. Type about:plugins in the urlbar to see what plugins are activated. |

Have jre and jdk without plugin support or better completely unmerged. No idea if any of your undisclosed browsers has java support without jre or jdk.
And, don't get confused regarding javascript being completely different from java. ok? |

I have the jdk and jre virtuals. How can I figure out which packages they are associated with? |

Available 32-bit Java browser plugins
Available 64-bit Java browser plugins |
I guess this means I don't have a jdk and jre? Why would I have the virtuals? My system is up to date and cleaned. |

Check | Code: | $ equery d virtual/jdk
$ equery d virtual/jre
$ grep -i 'jre\|jdk' /var/lib/portage/world |

| OK I can see that a java program I use does depend on virtual/jre, but then how can it operate without a real jre installed? |

The java program works for sure and I see that I do have dev-java/icedtea-7.2.4.7 installed, so I guess the question is why doesn't 'eselect java-nsplugin list' indicate that?
EDIT: It must be because I'm using USE="-nsplugin". Is there a method for finding out which jre and jdk are installed? |
