If you want to allow cups to execmem Then you must tell SELinux about this by enabling the 'cups_execmem' boolean. You can read 'None' man page for more details. Do setsebool -P cups_execmem 1 |
Description of problem: Trying to print to a network printer of Brother SELinux is preventing /usr/local/Brother/cupswrapper/brcupsconfig3 from using the 'execmem' accesses on a process. ***** Plugin catchall_boolean (89.3 confidence) suggests ****************** If you want to allow cups to execmem Then you must tell SELinux about this by enabling the 'cups_execmem' boolean. You can read 'None' man page for more details. Do setsebool -P cups_execmem 1 ***** Plugin catchall (11.6 confidence) suggests ************************** If you believe that brcupsconfig3 should be allowed execmem access on processes labeled cupsd_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 brcupsconfig3 /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:cupsd_t:s0-s0:c0.c1023 Target Context system_u:system_r:cupsd_t:s0-s0:c0.c1023 Target Objects Unknown [ process ] Source brcupsconfig3 Source Path /usr/local/Brother/cupswrapper/brcupsconfig3 Port <Unknown> Host (removed) Source RPM Packages brhl5250dnlpr-2.0.1-1.i386 Target RPM Packages Policy RPM selinux-policy-3.13.1-158.fc23.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.2.8-300.fc23.x86_64 #1 SMP Tue Dec 15 16:49:06 UTC 2015 x86_64 x86_64 Alert Count 21 First Seen 2015-12-07 00:14:59 IST Last Seen 2015-12-30 01:43:30 IST Local ID 12de6a6c-6e3b-42e7-a2fd-52e9c36f2abb Raw Audit Messages type=AVC msg=audit(1451432610.750:17680): avc: denied { execmem } for pid=30774 comm="rawtobr2" scontext=system_u:system_r:cupsd_t:s0-s0:c0.c1023 tcontext=system_u:system_r:cupsd_t:s0-s0:c0.c1023 tclass=process permissive=0 type=SYSCALL msg=audit(1451432610.750:17680): arch=x86_64 syscall=execve per=400000 success=no exit=EACCES a0=5564d5ff7450 a1=5564d5ff6c10 a2=5564d5ffaef0 a3=5564d5ff6c00 items=0 ppid=30740 pid=30774 auid=4294967295 uid=4 gid=7 euid=4 suid=4 fsuid=4 egid=7 sgid=7 fsgid=7 tty=(none) ses=4294967295 comm=rawtobr2 exe=/usr/local/Brother/lpd/rawtobr2 subj=system_u:system_r:cupsd_t:s0-s0:c0.c1023 key=(null) Hash: brcupsconfig3,cupsd_t,cupsd_t,process,execmem Version-Release number of selected component: selinux-policy-3.13.1-158.fc23.noarch Additional info: reporter: libreport-2.6.3 hashmarkername: setroubleshoot kernel: 4.2.8-300.fc23.x86_64 type: libreport Potential duplicate: bug 1251677
