A security issue has been reported in Gajim, which can be exploited by malicious, local users to perform certain actions with escalated privileges.

The security issue is caused due to the "get_tmpfile_name()" function (src/common/latex.py) creating temporary files in an insecure manner, which can be exploited to e.g. overwrite arbitrary files via symlink attacks.

The security issue is reported in version 0.15. Other versions may also be affected.

Solution
Fixed in the Mercurial repository.
