Hi,
When using mplayer for the past few days, I am getting the following
SELinux policy issue:
----
Summary:
SELinux is preventing totem-video-thu from loading
/usr/lib/sse2/libavformat.so.52.22.1 which requires text relocation.
Detailed Description:
The totem-video-thu application attempted to load
/usr/lib/sse2/libavformat.so.52.22.1 which requires text relocation.
This is a
potential security problem. Most libraries do not need this permission.
Libraries are sometimes coded incorrectly and request this permission. The
SELinux Memory Protection Tests
(http://people.redhat.com/drepper/selinux-mem.html) web page explains how to
remove this requirement. You can configure SELinux temporarily to allow
/usr/lib/sse2/libavformat.so.52.22.1 to use relocation as a workaround,
until
the library is fixed. Please file a bug report
(http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this package.
Allowing Access:
If you trust /usr/lib/sse2/libavformat.so.52.22.1 to run correctly, you can
change the file context to textrel_shlib_t. "chcon -t textrel_shlib_t
'/usr/lib/sse2/libavformat.so.52.22.1'" You must also change the default
file
context files on the system in order to preserve them even on a full
relabel.
"semanage fcontext -a -t textrel_shlib_t
'/usr/lib/sse2/libavformat.so.52.22.1'"
Fix Command:
chcon -t textrel_shlib_t '/usr/lib/sse2/libavformat.so.52.22.1'
