CRITICAL:
Not critical

Privilege escalation

Cecilia 2.x
http://secunia.com/product/18404/
DESCRIPTION:
Felipe Sateler has discovered a security issue in Cecilia, which can
be exploited by malicious, local users to perform certain actions
with escalated privileges.
The security issue is caused due to the "locateCsound()" function in
lib/prefs.tcl using the temporary file "/tmp/csvers" in an insecure
manner. This can be exploited to overwrite arbitrary files with the
privileges of the user running Cecilia.
The security issue is confirmed in version 2.0.5. Other versions may
also be affected.
SOLUTION:
Restrict access to trusted people only.
