NVD Description

Note: Versions mentioned in the description apply only to the upstream icedtea-web package and not the icedtea-web package as distributed by Debian. See How to fix? for Debian:14 relevant fixed versions and status.

The LiveConnect implementation in plugin/icedteanp/IcedTeaNPPlugin.cc in IcedTea-Web before 1.4.2 allows local users to read the messages between a Java applet and a web browser by pre-creating a temporary socket file with a predictable name in /tmp.
