Summary: SELinux is preventing /usr/lib64/nspluginwrapper/plugin-config from making the program stack executable. Detailed Description: [plugin-config has a permissive type (unconfined_t). This access was not denied.] The plugin-config application attempted to make its stack executable. This is a potential security problem. This should never ever be necessary. Stack memory is not executable on most OSes these days and this will not change. Executable stack memory is one of the biggest security problems. An execstack error might in fact be most likely raised by malicious code. Applications 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. If plugin-config does not work and you need it to work, you can configure SELinux temporarily to allow this access until the application is fixed. Please file a bug report. Allowing Access: Sometimes a library is accidentally marked with the execstack flag, if you find a library with this flag you can clear it with the execstack -c LIBRARY_PATH. Then retry your application. If the app continues to not work, you can turn the flag back on with execstack -s LIBRARY_PATH. Otherwise, if you trust plugin-config to run correctly, you can change the context of the executable to execmem_exec_t. "chcon -t execmem_exec_t '/usr/lib64/nspluginwrapper/plugin-config'" 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 execmem_exec_t '/usr/lib64/nspluginwrapper/plugin-config'" Fix Command: chcon -t execmem_exec_t '/usr/lib64/nspluginwrapper/plugin-config' Additional Information: Source Context unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1 023 Target Context unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1 023 Target Objects None [ process ] Source plugin-config Source Path /usr/lib64/nspluginwrapper/plugin-config Port <Unknown> Host (removed) Source RPM Packages nspluginwrapper-1.3.0-8.fc12 Target RPM Packages Policy RPM selinux-policy-3.6.32-46.fc12 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Plugin Name allow_execstack Host Name (removed) Platform Linux (removed) 2.6.31.5-127.fc12.x86_64 #1 SMP Sat Nov 7 21:11:14 EST 2009 x86_64 x86_64 Alert Count 6 First Seen Fri 20 Nov 2009 04:56:32 AM EET Last Seen Fri 20 Nov 2009 05:04:16 AM EET Local ID 9a0af16e-07b7-4e53-a9dc-2ab73033d166 Line Numbers Raw Audit Messages node=(removed) type=AVC msg=audit(1258686256.962:21206): avc: denied { execstack } for pid=2582 comm="plugin-config" scontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tcontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tclass=process node=(removed) type=SYSCALL msg=audit(1258686256.962:21206): arch=c000003e syscall=10 success=yes exit=128 a0=7fff702ae000 a1=1000 a2=1000007 a3=7f703626baeb items=0 ppid=2580 pid=2582 auid=500 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=pts1 ses=1 comm="plugin-config" exe="/usr/lib64/nspluginwrapper/plugin-config" subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 key=(null) Hash String generated from selinux-policy-3.6.32-46.fc12,allow_execstack,plugin-config,unconfined_t,unconfined_t,process,execstack audit2allow suggests: #============= unconfined_t ============== allow unconfined_t self:process execstack;

Yes but the outcome is the same. If you are using nvidia or some of the closed source fluendo codecs you need to turn on the allow_execstack boolean #setsebool -P allow_execstack 1
tengo probelamas con el repositorio, no puedo descargar acatualizaciones. que debo hacer para solucionar los problemas??? me aparece que el repositorio no esta configurado, por lo tanto, quise reinstalar el sistema operativo pero no pude por que me lanzaba errores al descargar paquetes. soy nuevo en fedora y necesito ayuda.
