Summary:

SELinux is preventing /usr/bin/avidemux2_qt4 from loading
/usr/lib/libADM5avcodec.so.52 which requires text relocation.

Detailed Description:

The avidemux2_qt4 application attempted to load /usr/lib/libADM5avcodec.so.52
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/libADM5avcodec.so.52 to use relocation as a workaround, until the
library is fixed. Please file a bug report.

Allowing Access:

If you trust /usr/lib/libADM5avcodec.so.52 to run correctly, you can change the
file context to textrel_shlib_t. "chcon -t textrel_shlib_t
'/usr/lib/libADM5avcodec.so.52'" 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/libADM5avcodec.so.52'"

Fix Command:

chcon -t textrel_shlib_t '/usr/lib/libADM5avcodec.so.52'
