A better fix is to label the acroread files correctly, which only
"opens" the protection for acroread and not every process on the system:
I believe you need:
# chcon -t textrel_shlib_t \
/usr/lib/acroread/Reader/intellinux/lib/*.so \
/usr/lib/acroread/Reader/intellinux/SPPlugins/*.apl \
/usr/lib/acroread/Reader/intellinux/plug_ins/*.api
I have checked that. As I am using the original RPM packets provided by Adobe
the files are located in /usr/local/Adobe/Acrobat7.0/Reader/intellinux and a
chcon -t textrel_shlib_t \
/usr/local/Adobe/Acrobat7.0/Reader/intellinux/lib/*.so
seems to be sufficient to run acroread and also use the plugin in Firefox.
BTW, what are SPPlugins and plug_ins for?
However, thank you Paul for providing this more customized solution. I assume,
that I only have to change the type context of the libraries distributed with
the Cisco VPN client accordingly to run it with a "fully" enabled selinux.
