SELinux is preventing /usr/local/MGLTools-1.5.4/bin/python from using the 'execstack' accesses on a process. ***** Plugin allow_execstack (53.1 confidence) suggests ******************** If you believe that None should not require execstack Then you should clear the execstack flag and see if /usr/local/MGLTools-1.5.4/bin/python works correctly. Report this as a bug on None. You can clear the exestack flag by executing: Do execstack -c None ***** 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 python /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 python Source Path /usr/local/MGLTools-1.5.4/bin/python Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.9.7-25.fc14 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux dahlia 2.6.35.10-74.fc14.i686.PAE #1 SMP Thu Dec 23 16:10:47 UTC 2010 i686 i686 Alert Count 4 First Seen Thu 14 Apr 2011 04:56:40 PM MYT Last Seen Thu 14 Apr 2011 05:05:14 PM MYT Local ID 797c8820-4818-4184-b4d3-f6493cf9cee3 Raw Audit Messages type=AVC msg=audit(1302771914.980:34276): avc: denied { execstack } for pid=3700 comm="python" scontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tcontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tclass=process type=SYSCALL msg=audit(1302771914.980:34276): arch=i386 syscall=mprotect success=no exit=EACCES a0=bff2f000 a1=1000 a2=1000007 a3=bff0d5c8 items=0 ppid=1 pid=3700 auid=501 uid=501 gid=501 euid=501 suid=501 fsuid=501 egid=501 sgid=501 fsgid=501 tty=(none) ses=1 comm=python exe=/usr/local/MGLTools-1.5.4/bin/python subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 key=(null) Hash: python,unconfined_t,unconfined_t,process,execstack audit2allow #============= unconfined_t ============== #!!!!
