Sumário: SELinux is preventing /usr/lib/nspluginwrapper/plugin-config from making the program stack executable. Descrição detalhada: 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. Permitindo acesso: 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/lib/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/lib/nspluginwrapper/plugin-config'" Comando de correção: chcon -t execmem_exec_t '/usr/lib/nspluginwrapper/plugin-config' Informações adicionais: Contexto de origem unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1 023 Contexto de destino unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1 023 Objetos de destino None [ process ] Origem scalc.bin Caminho da origem /usr/lib/broffice.org3/program/scalc.bin Porta <Desconhecido> Máquina (removed) Pacotes RPM de origem nspluginwrapper-1.3.0-8.fc12 Pacotes RPM de destino RPM da política selinux-policy-3.6.32-46.fc12 Selinux habilitado True Tipo de política targeted Modo reforçado Enforcing Nome do plugin allow_execstack Nome da máquina (removed) Plataforma Linux (removed) 2.6.31.5-127.fc12.i686 #1 SMP Sat Nov 7 21:41:45 EST 2009 i686 i686 Contador de alertas 17 Visto pela primeira vez em Ter 24 Nov 2009 22:42:04 BRT Visto pela última vez em Qua 25 Nov 2009 22:34:16 BRT ID local 3afb1ca7-362a-4f65-b096-8b2e290a16a9 Números de linha Mensagens de auditoria não p node=(removed) type=AVC msg=audit(1259199256.290:21056): avc: denied { execstack } for pid=2500 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(1259199256.290:21056): arch=40000003 syscall=125 success=no exit=-13 a0=bfdd0000 a1=1000 a2=1000007 a3=bfdc7af0 items=0 ppid=2498 pid=2500 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-3.6.32-46.fc12,allow_execstack,scalc.bin,unconfined_t,unconfined_t,process,execstack audit2allow suggests: #============= unconfined_t ============== allow unconfined_t self:process execstack;
