Summary: SELinux is preventing flock-bin from loading /usr/lib/firefox/plugins/libractrl.so which requires text relocation. Detailed Description: The flock-bin 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 (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this package. 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 Target Context system_u:object_r:lib_t:s0 Target Objects /usr/lib/firefox/plugins/libractrl.so [ file ] Source npviewer.bin Source Path /usr/lib/nspluginwrapper/npviewer.bin Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages logmein-client-1.0.387-1 Policy RPM selinux-policy-3.5.13-53.fc10 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Plugin Name allow_execmod Host Name (removed) Platform Linux (removed) 2.6.27.21-170.2.56.fc10.i686 #1 SMP Mon Mar 23 23:37:54 EDT 2009 i686 i686 Alert Count 14 First Seen Mon 12 Jan 2009 12:29:34 PM GMT Last Seen Fri 03 Apr 2009 03:16:43 PM BST Local ID 9ede610c-2f83-4ca9-a7c0-c01cdfe63109 Line Numbers Raw Audit Messages node=(removed) type=AVC msg=audit(1238768203.534:43): avc: denied { execmod } for pid=3286 comm="flock-bin" path="/usr/lib/firefox/plugins/libractrl.so" dev=dm-0 ino=23601640 scontext=unconfined_u:unconfined_r:unconfined_t:s0 tcontext=system_u:object_r:lib_t:s0 tclass=file node=(removed) type=SYSCALL msg=audit(1238768203.534:43): arch=40000003 syscall=125 success=no exit=-13 a0=48e0000 a1=694000 a2=5 a3=bfe99f50 items=0 ppid=3280 pid=3286 auid=500 uid=500 gid=500 euid=500 suid=500 fsuid=500 egid=500 sgid=500 fsgid=500 tty=(none) ses=1 comm="flock-bin" exe="/usr/lib/flock/flock-bin" subj=unconfined_u:unconfined_r:unconfined_t:s0 key=(null) Hash String generated from selinux-policy-3.5.13-53.fc10,allow_execmod,npviewer.bin,unconfined_t,lib_t,file,execmod audit2allow suggests: #============= unconfined_t ============== allow unconfined_t lib_t:file execmod;
