-------------------------------------
Summary: guacd 1.5.4/master double free issue
Key: GUACAMOLE-1903
URL: https://issues.apache.org/jira/browse/GUACAMOLE-1903
Project: Guacamole
Issue Type: Bug
Components: guacamole-server
Affects Versions: 1.5.4
Reporter: Simon Vogl
Attachments: drd.log
Hi all,
we have a running 1.4 installation that serves vnc connections (only). I am
trying to upgrade to a recent code basis as we want to add some features
(alt-f4 etc on the OSD).
I installed client and server versions 1.5.4 on a test machine and it works
only for some of our client boxes (ones in our office,p.ex.) but guacd dies for
other connections (at a remote site behind a firewall) with a 'double free'
error. Guacd seemingly dies when cursor movements happen on the web client, and
I saw it happen consistently when the mouse enters / leaves the rendered remote
display in the browser window.
I ran guacd with the valgrind drd tool
valgrind --tool=drd --trace-fork-join=yes /usr/local/sbin/guacd-1.5.4a -f -L
trace -b 127.0.0.1 -l 4822 -p /tmp/guacd.pid
and captured the state in the attachmed drd.log when guacd died away.
