Summary: SELinux is preventing tcmodinfo from loading /usr/lib/transcode/filter_yuvdenoise.so which requires text relocation. Detailed Description: The tcmodinfo application attempted to load /usr/lib/transcode/filter_yuvdenoise.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/transcode/filter_yuvdenoise.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/transcode/filter_yuvdenoise.so to run correctly, you can change the file context to textrel_shlib_t. "chcon -t textrel_shlib_t '/usr/lib/transcode/filter_yuvdenoise.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/transcode/filter_yuvdenoise.so'" Fix Command: chcon -t textrel_shlib_t '/usr/lib/transcode/filter_yuvdenoise.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/transcode/filter_yuvdenoise.so [ file ] Source tcmodinfo Source Path /usr/bin/tcmodinfo Port <Unknown> Host (removed) Source RPM Packages transcode-1.1.1-5.fc11 Target RPM Packages transcode-1.1.1-5.fc11 Policy RPM selinux-policy-3.6.12-39.fc11 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Plugin Name allow_execmod Host Name (removed) Platform Linux (removed) 2.6.29.5-191.fc11.i686.PAE #1 SMP Tue Jun 16 23:19:53 EDT 2009 i686 i686 Alert Count 1 First Seen Sun 05 Jul 2009 04:38:42 PM IST Last Seen Sun 05 Jul 2009 04:38:42 PM IST Local ID a982eb7f-43af-4313-9474-03ae2912e30a Line Numbers Raw Audit Messages node=(removed) type=AVC msg=audit(1246792122.275:82): avc: denied { execmod } for pid=12499 comm="tcmodinfo" path="/usr/lib/transcode/filter_yuvdenoise.so" dev=sda3 ino=189472 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(1246792122.275:82): arch=40000003 syscall=125 success=no exit=-13 a0=d65000 a1=36000 a2=5 a3=bfe7b250 items=0 ppid=12498 pid=12499 auid=500 uid=500 gid=500 euid=500 suid=500 fsuid=500 egid=500 sgid=500 fsgid=500 tty=(none) ses=1 comm="tcmodinfo" exe="/usr/bin/tcmodinfo" subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 key=(null) Hash String generated from selinux-policy-3.6.12-39.fc11,allow_execmod,tcmodinfo,unconfined_t,lib_t,file,execmod audit2allow suggests: #============= unconfined_t ============== allow unconfined_t lib_t:file execmod;
