Description of problem: SELinux is preventing 536F636B657420546872656164 from 'mmap_zero' accesses on the memprotect . ***** Plugin mmap_zero (53.1 confidence) suggests ************************** If you do not think 536F636B657420546872656164 should need to mmap low memory in the kernel. Then you may be under attack by a hacker, this is a very dangerous access. Do contact your security administrator and report this issue. ***** Plugin catchall_boolean (42.6 confidence) suggests ******************* If you want to control the ability to mmap a low area of the address space, as configured by /proc/sys/kernel/mmap_min_addr. Then you must tell SELinux about this by enabling the 'mmap_low_allowed' boolean. You can read 'unconfined_selinux' man page for more details. Do setsebool -P mmap_low_allowed 1 ***** Plugin catchall (5.76 confidence) suggests *************************** If you believe that 536F636B657420546872656164 should be allowed mmap_zero access on the memprotect 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 536F636B657420546872656164 /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 [ memprotect ] Source 536F636B657420546872656164 Source Path 536F636B657420546872656164 Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.12.1-44.fc19.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 3.9.2-301.fc19.i686.PAE #1 SMP Mon May 13 12:47:57 UTC 2013 i686 i686 Alert Count 4 First Seen 2013-05-19 15:10:45 YEKT Last Seen 2013-05-21 00:44:12 YEKT Local ID 16bb6fca-ab56-4ef7-b4de-b2e58531249a Raw Audit Messages type=AVC msg=audit(1369075452.523:1041): avc: denied { mmap_zero } for pid=19596 comm="wine-preloader" scontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tcontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tclass=memprotect Hash: 536F636B657420546872656164,unconfined_t,unconfined_t,memprotect,mmap_zero audit2allow #============= unconfined_t ============== #!!!!
