Description Sami Keski-Kasari 2005-06-14 14:55:57 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050513 Fedora/1.0.4-1.3.1 Firefox/1.0.4

Description of problem:
I updated today selinux-policy-targeted to 1.17.30-3.2.
After upgrade Macromedia flashplayer doesn't work anymore. 

In dmesg there is error message:
audit(1118774466.618:0): avc:  denied  { execmod } for  pid=4806 comm=firefox-bin path=/home/samikk/.mozilla/plugins/libflashplayer.so dev=hdh6 ino=227461 scontext=user_u:system_r:unconfined_t tcontext=user_u:object_r:user_home_t tclass=file

ls -laZ in /home/samikk/.mozilla/plugins/ says

-rw-r--r--  samikk   samikk   user_u:object_r:user_home_t      flashplayer.xpt
-rwxr-xr-x  samikk   samikk   user_u:object_r:user_home_t      libflashplayer.so

I tried to reinstall flashplayer via firefox software installer but it didn't help.

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

How reproducible:

Steps to Reproduce:
1.install flashplayer plugin

If you execute 

setsebool -P allow_execmod=1

as root, Does that fix the problem?

No it doesn't

After that command in dmesg there is message:
security: committed booleans { allow_execstack:1, allow_execmem:1, allow_execmod
:1, use_nfs_home_dirs:0, use_samba_home_dirs:0, allow_ypbind:1, allow_kerberos:1

id_disable_trans:0, syslogd_disable_trans:0, use_syslogng:0, winbind_disable_tra
ns:0, ypbind_disable_trans:0 }

But when I restart firefox there comes still same error message:
audit(1118859238.775:0): avc:  denied  { execmod } for  pid=6621 comm=firefox-bi

Yes, it works again with that version

Comment 5 Keunwoo Lee 2005-07-01 14:20:16 EDT
Broken again in selinux-policy-targeted-1.17.30-3.13.  Flash plugin doesn't
work, and doing /usr/sbin/setenforce 0 makes it work.
