Summary: SELinux is preventing avidemux2_gtk from loading /usr/lib/ADM_plugins/videoFilter/libADM_vf_FluxSmooth.so which requires text relocation. Detailed Description: [SELinux is in permissive mode. This access was not denied.] The avidemux2_gtk application attempted to load /usr/lib/ADM_plugins/videoFilter/libADM_vf_FluxSmooth.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/lib/ADM_plugins/videoFilter/libADM_vf_FluxSmooth.so 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/ADM_plugins/videoFilter/libADM_vf_FluxSmooth.so to run correctly, you can change the file context to textrel_shlib_t. "chcon -t textrel_shlib_t '/usr/lib/ADM_plugins/videoFilter/libADM_vf_FluxSmooth.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/lib/ADM_plugins/videoFilter/libADM_vf_FluxSmooth.so'" Fix Command: chcon -t textrel_shlib_t '/usr/lib/ADM_plugins/videoFilter/libADM_vf_FluxSmooth.so' Additional Information: Source Context unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1 023 Target Context system_u:object_r:lib_t:s0 Target Objects /usr/lib/ADM_plugins/videoFilter/libADM_vf_FluxSmo oth.so [ file ] Source avidemux2_gtk Source Path /usr/bin/avidemux2_gtk Port <Unknown> Host (removed) Source RPM Packages avidemux-gtk-2.5.1-3.20091010svn.fc11 Target RPM Packages avidemux-plugins-2.5.1-3.20091010svn.fc11 Policy RPM selinux-policy-3.6.12-88.fc11 Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Plugin Name allow_execmod Host Name (removed) Platform Linux (removed) 2.6.30.9-96.fc11.i686.PAE #1 SMP Tue Nov 3 23:41:33 EST 2009 i686 i686 Alert Count 5 First Seen Sun 08 Nov 2009 10:49:57 PM CET Last Seen Wed 11 Nov 2009 09:50:41 PM CET Local ID bf0d36b9-d8fa-4f49-a983-1c91f6553cc0 Line Numbers Raw Audit Messages node=(removed) type=AVC msg=audit(1257972641.738:256): avc: denied { execmod } for pid=4748 comm="avidemux2_gtk" path="/usr/lib/ADM_plugins/videoFilter/libADM_vf_FluxSmooth.so" dev=sda3 ino=8929016 scontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tcontext=system_u:object_r:lib_t:s0 tclass=file node=(removed) type=SYSCALL msg=audit(1257972641.738:256): arch=40000003 syscall=125 success=yes exit=0 a0=fb0000 a1=3000 a2=5 a3=bfef1230 items=0 ppid=1 pid=4748 auid=500 uid=500 gid=500 euid=500 suid=500 fsuid=500 egid=500 sgid=500 fsgid=500 tty=(none) ses=1 comm="avidemux2_gtk" exe="/usr/bin/avidemux2_gtk" subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 key=(null) Hash String generated from selinux-policy-3.6.12-88.fc11,allow_execmod,avidemux2_gtk,unconfined_t,lib_t,file,execmod audit2allow suggests: #============= unconfined_t ============== allow unconfined_t lib_t:file execmod;
Do what the sealert suggests. I will fix the labeling in the next update. Fixed in selinux-policy-3.6.32-48.fc12.noarch
