SELinux is preventing /usr/bin/liferea from using the 'execstack' accesses on a process. ***** Plugin allow_execstack (53.1 confidence) suggests ******************** If you do not think /usr/bin/liferea should need to map stack memory that is both writable and executable. Then you need to report a bug. This is a potentially dangerous access. Do contact your security administrator and report this issue. ***** Plugin catchall_boolean (42.6 confidence) suggests ******************* If you want to 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 Then you must tell SELinux about this by enabling the 'allow_execstack' boolean. Do setsebool -P allow_execstack 1 ***** Plugin catchall (5.76 confidence) suggests *************************** If you believe that liferea should be allowed execstack access on processes labeled unconfined_t by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # grep /usr/bin/liferea /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp 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 Unknown [ process ] Source liferea Source Path /usr/bin/liferea Port <Desconocido> Host (removed) Source RPM Packages liferea-1.6.5-1.fc14 Target RPM Packages Policy RPM selinux-policy-3.9.7-18.fc14 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 2.6.34.7-61.fc13.i686 #1 SMP Tue Oct 19 04:42:47 UTC 2010 i686 i686 Alert Count 2 First Seen jue 23 dic 2010 16:57:30 VET Last Seen jue 23 dic 2010 16:57:30 VET Local ID c0b2e89c-0293-46f4-9388-4d5a14f963db Raw Audit Messages type=AVC msg=audit(1293139650.385:24): avc: denied { execstack } for pid=3236 comm="liferea" scontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tcontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tclass=process liferea,unconfined_t,unconfined_t,process,execstack type=SYSCALL msg=audit(1293139650.385:24): arch=i386 syscall=mprotect success=no exit=EACCES a0=bfdc9000 a1=1000 a2=1000007 a3=bfdc7e60 items=0 ppid=1 pid=3236 auid=500 uid=500 gid=500 euid=500 suid=500 fsuid=500 egid=500 sgid=500 fsgid=500 tty=(none) ses=1 comm=liferea exe=/usr/bin/liferea subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 key=(null) liferea,unconfined_t,unconfined_t,process,execstack #============= unconfined_t ============== #!!!!
