Summary: SELinux is preventing /usr/lib/nspluginwrapper/plugin-config from loading /usr/lib/firefox/plugins/libractrl.so which requires text relocation. Detailed Description: The plugin-config application attempted to load /usr/lib/firefox/plugins/libractrl.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/firefox/plugins/libractrl.so to use relocation as a workaround, until the library is fixed. Please file a bug report. Allowing Access: If you trust /usr/lib/firefox/plugins/libractrl.so to run correctly, you can change the file context to textrel_shlib_t. "chcon -t textrel_shlib_t '/usr/lib/firefox/plugins/libractrl.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/firefox/plugins/libractrl.so'" Fix Command: chcon -t textrel_shlib_t '/usr/lib/firefox/plugins/libractrl.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/firefox/plugins/libractrl.so [ file ] Source plugin-config Source Path /usr/lib/nspluginwrapper/plugin-config Port <Unknown> Host (removed) Source RPM Packages nspluginwrapper-1.3.0-10.fc12 Target RPM Packages logmein-client-1.0.387-1 Policy RPM selinux-policy-3.6.32-59.fc12 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Plugin Name allow_execmod Host Name (removed) Platform Linux (removed) 2.6.31.9-174.fc12.i686.PAE #1 SMP Mon Dec 21 06:04:56 UTC 2009 i686 i686 Alert Count 1 First Seen Wed 30 Dec 2009 07:05:23 PM MST Last Seen Wed 30 Dec 2009 07:05:23 PM MST Local ID 424d4f02-cdb5-4b75-8004-1371943b8c2b Line Numbers Raw Audit Messages node=(removed) type=AVC msg=audit(1262225123.136:25208): avc: denied { execmod } for pid=2584 comm="plugin-config" path="/usr/lib/firefox/plugins/libractrl.so" dev=dm-0 ino=2098639 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(1262225123.136:25208): arch=40000003 syscall=125 success=no exit=-13 a0=cdb000 a1=694000 a2=5 a3=bfe46b40 items=0 ppid=2582 pid=2584 auid=500 uid=500 gid=500 euid=0 suid=0 fsuid=0 egid=500 sgid=500 fsgid=500 tty=(none) ses=1 comm="plugin-config" exe="/usr/lib/nspluginwrapper/plugin-config" subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 key=(null) Hash String generated from selinux-policy-3.6.32-59.fc12,allow_execmod,plugin-config,unconfined_t,lib_t,file,execmod audit2allow suggests: audit2allow is not installed.
"/usr/lib/firefox/plugins/libractrl.so is built incorrectly, report this problem to the people who built it. Execute the chcon command in the sealert, which will allow you to use the library. I will make this the default label. Fixed in selinux-policy-3.6.32-65.fc12.noarch
