Description of problem: SELinux is preventing wine-preloader from 'mmap_zero' accesses on the memprotect . ***** Plugin mmap_zero (53.1 confidence) suggests ************************** If you do not think wine-preloader 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 'wine_selinux' man page for more details. Do setsebool -P mmap_low_allowed 1 ***** Plugin catchall (5.76 confidence) suggests *************************** If you believe that wine-preloader 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 wine-preloader /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context unconfined_u:unconfined_r:wine_t:s0-s0:c0.c1023 Target Context unconfined_u:unconfined_r:wine_t:s0-s0:c0.c1023 Target Objects [ memprotect ] Source wine-preloader Source Path wine-preloader Port <Unknown> Host (removed) Source RPM Packages wine-core-1.5.29-1.fc18.i686 Target RPM Packages Policy RPM selinux-policy-3.11.1-97.fc18.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 3.9.6-200.fc18.x86_64 #1 SMP Thu Jun 13 18:56:55 UTC 2013 x86_64 x86_64 Alert Count 722185 First Seen 2013-04-21 11:04:43 EEST Last Seen 2013-06-25 01:10:53 EEST Local ID dbe65e37-6a06-4fac-9d69-d4570663746a Raw Audit Messages type=AVC msg=audit(1372111853.70:476): avc: denied { mmap_zero } for pid=9198 comm="wine-preloader" scontext=unconfined_u:unconfined_r:wine_t:s0-s0:c0.c1023 tcontext=unconfined_u:unconfined_r:wine_t:s0-s0:c0.c1023 tclass=memprotect type=SYSCALL msg=audit(1372111853.70:476): arch=i386 syscall=chmod success=no exit=EACCES a0=ffc26f90 a1=ffc26f90 a2=0 a3=ffc271ac items=0 ppid=1 pid=9198 auid=1000 uid=1000 gid=1000 euid=1000 suid=1000 fsuid=1000 egid=1000 sgid=1000 fsgid=1000 ses=2 tty=(none) comm=wine-preloader exe=/usr/bin/wine-preloader subj=unconfined_u:unconfined_r:wine_t:s0-s0:c0.c1023 key=(null) Hash: wine-preloader,wine_t,wine_t,memprotect,mmap_zero Additional info: reporter: libreport-2.1.6 hashmarkername: setroubleshoot kernel: 3.10.9-200.fc19.x86_64 type: libreport Potential duplicate: bug 665145
