The plugin tells you what to do. # setsebool -P allow_execheap 1 if you want to allow this access. |
SELinux is preventing /home/slawomir/Oolite/oolite.app/oolite from using the 'execheap' accesses on a process. ***** Plugin allow_execheap (53.1 confidence) suggests ********************* If you do not think /home/slawomir/Oolite/oolite.app/oolite should need to map heap 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 heap memory executable. Doing this is a really bad idea. 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_execheap' boolean. Do setsebool -P allow_execheap 1 ***** Plugin catchall (5.76 confidence) suggests *************************** If you believe that oolite should be allowed execheap 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 oolite /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 oolite Source Path /home/slawomir/Oolite/oolite.app/oolite Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.9.16-35.fc15 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 2.6.40.3-0.scw20110826.fc15.i686.PAE #1 SMP Fri Aug 26 11:48:39 CEST 2011 i686 i686 Alert Count 1 First Seen Sun 28 Aug 2011 07:58:48 PM CEST Last Seen Sun 28 Aug 2011 07:58:48 PM CEST Local ID da3c3507-8cd6-4498-bff5-91cf49127a83 Raw Audit Messages type=AVC msg=audit(1314554328.505:1068): avc: denied { execheap } for pid=28188 comm="oolite" 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(1314554328.505:1068): arch=i386 syscall=mprotect success=no exit=EACCES a0=a011000 a1=1000 a2=7 a3=a011000 items=0 ppid=28183 pid=28188 auid=2026 uid=2026 gid=2027 euid=2026 suid=2026 fsuid=2026 egid=2027 sgid=2027 fsgid=2027 tty=pts1 ses=1 comm=oolite exe=/home/slawomir/Oolite/oolite.app/oolite subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 key=(null) Hash: oolite,unconfined_t,unconfined_t,process,execheap audit2allow #============= unconfined_t ============== #!!!!
