SELinux is preventing /usr/bin/python from using the 'execstack' accesses on a process. ***** Plugin allow_execstack (53.1 confidence) suggests ******************** If you do not think /usr/bin/python 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 python 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 wavparse2:sink /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 wavparse2:sink Source Path /usr/bin/python Port <Desconocido> Host (removed) Source RPM Packages mencoder-1.0-0.119.20100703svn.fc14 Target RPM Packages Policy RPM selinux-policy-3.9.7-20.fc14 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 2.6.35.10-74.fc14.i686 #1 SMP Thu Dec 23 16:17:40 UTC 2010 i686 i686 Alert Count 13886 First Seen mié 29 dic 2010 17:36:18 MST Last Seen sáb 22 ene 2011 10:29:41 MST Local ID 79fc59b9-eba6-4c55-9ab6-c8862e8613b7 Raw Audit Messages type=AVC msg=audit(1295717381.681:25387): avc: denied { execstack } for pid=2594 comm="mencoder" scontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tcontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tclass=process wavparse2:sink,unconfined_t,unconfined_t,process,execstack type=SYSCALL msg=audit(1295717381.681:25387): arch=i386 syscall=mprotect success=no exit=EACCES a0=bff9b000 a1=1000 a2=1000007 a3=bff9b260 items=0 ppid=2593 pid=2594 auid=500 uid=500 gid=500 euid=500 suid=500 fsuid=500 egid=500 sgid=500 fsgid=500 tty=pts0 ses=1 comm=mencoder exe=/usr/bin/mencoder subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 key=(null) wavparse2:sink,unconfined_t,unconfined_t,process,execstack #============= unconfined_t ============== #!!!!
