Sumário:

SELinux is preventing /usr/lib64/chromium-browser/chromium-browser from loading
/usr/lib64/chromium-browser/libsandbox.so which requires text relocation.

Descrição detalhada:

[chromium-browse tem um tipo permissivo (chrome_sandbox_t). Esse acesso não foi
negado.]

The chromium-browse application attempted to load
/usr/lib64/chromium-browser/libsandbox.so 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/lib64/chromium-browser/libsandbox.so to use relocation as a workaround,
until the library is fixed. Please file a bug report.

Permitindo acesso:

If you trust /usr/lib64/chromium-browser/libsandbox.so to run correctly, you can
change the file context to textrel_shlib_t. "chcon -t textrel_shlib_t
'/usr/lib64/chromium-browser/libsandbox.so'" 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/lib64/chromium-browser/libsandbox.so'"

Comando de correção:

chcon -t textrel_shlib_t '/usr/lib64/chromium-browser/libsandbox.so'
