sellinux attachmet failed to load with bug report, cut and paste follows below: Summary: SELinux is preventing nautilus from loading /usr/lib/sse2/libpostproc.so.51.2.0 which requires text relocation. Detailed Description: The nautilus application attempted to load /usr/lib/sse2/libpostproc.so.51.2.0 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/sse2/libpostproc.so.51.2.0 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/sse2/libpostproc.so.51.2.0 to run correctly, you can change the file context to textrel_shlib_t. "chcon -t textrel_shlib_t '/usr/lib/sse2/libpostproc.so.51.2.0'" 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/sse2/libpostproc.so.51.2.0'" Fix Command: chcon -t textrel_shlib_t '/usr/lib/sse2/libpostproc.so.51.2.0' Additional Information: Source Context unconfined_u:unconfined_r:unconfined_t:s0 Target Context system_u:object_r:lib_t:s0 Target Objects /usr/lib/sse2/libpostproc.so.51.2.0 [ file ] Source totem Source Path /usr/bin/totem Port <Unknown> Host venice.gwirynybyd.com Source RPM Packages nautilus-2.24.1-3.fc10 Target RPM Packages ffmpeg-libs-0.4.9-0.52.20080908.fc10 Policy RPM selinux-policy-3.5.13-18.fc10 Selinux Enabled True Policy Type targeted MLS Enabled True Enforcing Mode Enforcing Plugin Name allow_execmod Host Name venice.gwirynybyd.com Platform Linux venice.gwirynybyd.com 2.6.27.5-117.fc10.i686 #1 SMP Tue Nov 18 12:19:59 EST 2008 i686 i686 Alert Count 3 First Seen Sat 29 Nov 2008 07:41:33 PM PST Last Seen Sat 29 Nov 2008 07:44:16 PM PST Local ID a5dce2a0-e80e-4804-b8db-f275495b180f Line Numbers Raw Audit Messages node=venice.gwirynybyd.com type=AVC msg=audit(1228016656.317:48): avc: denied { execmod } for pid=21039 comm="nautilus" path="/usr/lib/sse2/libpostproc.so.51.2.0" dev=sda7 ino=991268 scontext=unconfined_u:unconfined_r:unconfined_t:s0 tcontext=system_u:object_r:lib_t:s0 tclass=file node=venice.gwirynybyd.com type=SYSCALL msg=audit(1228016656.317:48): arch=40000003 syscall=125 success=no exit=-13 a0=6884000 a1=9000 a2=5 a3=bfec5b00 items=0 ppid=2675 pid=21039 auid=500 uid=500 gid=500 euid=500 suid=500 fsuid=500 egid=500 sgid=500 fsgid=500 tty=(none) ses=1 comm="nautilus" exe="/usr/bin/nautilus" subj=unconfined_u:unconfined_r:unconfined_t:s0 key=(null) This is due to a 3rd-party GStreamer plugin not Totem, or nautilus. |
