This is a bug in yelp or some library that it is causing. We have changed the default for Fedora 12 to enabel allow_execmem boolean because of badly written code. You should probably just turn on this boolean setsebool -P allow_execmem 1 execmem has also been caused by the nvidia device drivers. *** This bug has been marked as a duplicate of bug 507023 *** |
Resúmen: SELinux is preventing /usr/bin/yelp "execmem" access on <Unknown>. Descripción Detallada: SELinux denied access requested by yelp. The current boolean settings do not allow this access. If you have not setup yelp to require this access this may signal an intrusion attempt. If you do intend this access you need to change the booleans on this system to allow the access. Permitiendo Acceso: One of the following booleans is set incorrectly: allow_execstack, allow_execmem Comando para Corregir: Choose one of the following to allow access: Allow unconfined executables to make their stack executable. This should never, ever be necessary. Probably indicates a badly coded executable, but could indicate an attack. This executable should be reported in bugzilla") # setsebool -P allow_execstack 1 Allow unconfined executables to map a memory region as both executable and writable, this is dangerous and the executable should be reported in bugzilla") # setsebool -P allow_execmem 1 Información Adicional: Contexto Fuente unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1 023 Contexto Destino unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1 023 Objetos Destino None [ process ] Fuente yelp Dirección de Fuente /usr/bin/yelp Puerto <Desconocido> Nombre de Equipo (removed) Paquetes RPM Fuentes yelp-2.28.0-1.fc12 Paquetes RPM Destinos RPM de Políticas selinux-policy-3.6.32-24.fc12 SELinux Activado True Tipo de Política targeted MLS Activado True Modo Obediente Enforcing Nombre de Plugin catchall_boolean Nombre de Equipo (removed) Plataforma Linux (removed) 2.6.31.1-56.fc12.i686 #1 SMP Tue Sep 29 16:32:02 EDT 2009 i686 athlon Cantidad de Alertas 3 Visto por Primera Vez dom 25 oct 2009 21:26:22 EDT Visto por Última Vez dom 25 oct 2009 21:26:22 EDT ID Local e16cae7f-39d3-44ae-8a1d-69707f1d9ee1 Números de Línea Mensajes de Auditoría Crudos node=(removed) type=AVC msg=audit(1256520382.315:24181): avc: denied { execmem } for pid=2470 comm="yelp" 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(1256520382.315:24181): arch=40000003 syscall=192 success=no exit=-13 a0=0 a1=1000 a2=7 a3=22 items=0 ppid=1 pid=2470 auid=500 uid=500 gid=500 euid=500 suid=500 fsuid=500 egid=500 sgid=500 fsgid=500 tty=(none) ses=1 comm="yelp" exe="/usr/bin/yelp" subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 key=(null) Hash String generated from selinux-policy-3.6.32-24.fc12,catchall_boolean,yelp,unconfined_t,unconfined_t,process,execmem audit2allow suggests: #============= unconfined_t ============== allow unconfined_t self:process execmem;
