Description Peter Mackenzie 2008-03-20 21:26:25 EDT
Description of problem:
SELinux is preventing /usr/local/matlab2007b/bin/glnxa64/MATLAB from changing
the access protection of memory on the heap.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. start matlab version R2007b
2. open any figure or edit window etc.
Actual results:
The /usr/local/matlab2007b/bin/glnxa64/MATLAB application attempted to change
the access protection of memory on the heap (e,g., allocated using malloc). This
is a potential security problem. Applications should not be doing this.
Applications are sometimes coded incorrectly and request this permission. The
SELinux Memory Protection Tests web page explains how to remove this
requirement. If /usr/local/matlab2007b/bin/glnxa64/MATLAB does not work and you
need it to work, you can configure SELinux temporarily to allow this access
until the application is fixed. Please file a bug report against this package.

Expected results:

Additional info:
Comment 1 Daniel Walsh 2008-03-21 06:39:25 EDT
chcon -t java_exec_t /usr/local/matlab2007b/bin/glnxa64/MATLAB

Should fix it.

I will try to fix this mapping in U2 policy
Comment 2 Daniel Walsh 2008-04-07 21:45:40 EDT
Fixed mapping in selinux-policy-2.4.6-128.el5
