***** Plugin catchall_boolean (42.6 confidence) suggests ****************** If you want to allow selinuxuser to execheap Then you must tell SELinux about this by enabling the 'selinuxuser_execheap' boolean. Do setsebool -P selinuxuser_execheap 1 |
Description of problem: launched insurgency via steam. SELinux is preventing hl_linux from using the 'execheap' accesses on a process. ***** Plugin allow_execheap (53.1 confidence) suggests ******************** If you do not think hl_linux 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 selinuxuser to execheap Then you must tell SELinux about this by enabling the 'selinuxuser_execheap' boolean. Do setsebool -P selinuxuser_execheap 1 ***** Plugin catchall (5.76 confidence) suggests ************************** If you believe that hl_linux 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: # ausearch -c 'hl_linux' --raw | audit2allow -M my-hllinux # semodule -X 300 -i my-hllinux.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 hl_linux Source Path hl_linux Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.13.1-260.9.fc26.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.12.13-300.fc26.x86_64 #1 SMP Thu Sep 14 16:00:38 UTC 2017 x86_64 x86_64 Alert Count 3 First Seen 2017-09-23 00:18:26 MDT Last Seen 2017-09-23 17:30:03 MDT Local ID 5c93bdb3-c701-4b53-aedb-77d10b1ed469 Raw Audit Messages type=AVC msg=audit(1506209403.17:484): avc: denied { execheap } for pid=18987 comm="hl_linux" scontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tcontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tclass=process permissive=0 Hash: hl_linux,unconfined_t,unconfined_t,process,execheap Version-Release number of selected component: selinux-policy-3.13.1-260.9.fc26.noarch Additional info: component: selinux-policy reporter: libreport-2.9.1 hashmarkername: setroubleshoot kernel: 4.13.5-200.fc26.x86_64 type: libreport Potential duplicate: bug 907379
