Description
The register_application function in atk-adaptor/bridge.c in GNOME at-spi2-atk 2.5.2 does not seed the random number generator and generates predictable temporary file names, which makes it easier for local users to create or truncate files via a symlink attack on a temporary socket file in /tmp/at-spi2.
