Description of problem: usb drive plugged in. Additional info: reporter: libreport-2.1.4 hashmarkername: setroubleshoot kernel: 3.9.2-200.fc18.i686 type: libreport This message is a reminder that Fedora 18 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 18. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '18'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 18's end of life. Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 18 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior to Fedora 18's end of life. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. Fedora 18 changed to end-of-life (EOL) status on 2014-01-14. Fedora 18 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed. |
Description of problem: plugged in a USB drive SELinux is preventing /usr/bin/evince-thumbnailer from 'execute' accesses on the chr_file /dev/zero. ***** Plugin catchall (100. confidence) suggests *************************** If you believe that evince-thumbnailer should be allowed execute access on the zero chr_file 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 evince-thumbnai /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context unconfined_u:unconfined_r:thumb_t:s0-s0:c0.c1023 Target Context system_u:object_r:zero_device_t:s0 Target Objects /dev/zero [ chr_file ] Source evince-thumbnai Source Path /usr/bin/evince-thumbnailer Port <Unknown> Host (removed) Source RPM Packages evince-3.6.1-2.fc18.i686 Target RPM Packages Policy RPM selinux-policy-3.11.1-94.fc18.noarch selinux- policy-3.11.1-95.fc18.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 3.9.2-200.fc18.i686 #1 SMP Mon May 13 14:48:23 UTC 2013 i686 i686 Alert Count 7 First Seen 2013-05-21 16:16:51 EDT Last Seen 2013-05-21 16:17:08 EDT Local ID de2676ae-e172-4157-8bec-69c9ec6ece0a Raw Audit Messages type=AVC msg=audit(1369167428.570:531): avc: denied { execute } for pid=3775 comm="evince-thumbnai" path="/dev/zero" dev="devtmpfs" ino=4708 scontext=unconfined_u:unconfined_r:thumb_t:s0-s0:c0.c1023 tcontext=system_u:object_r:zero_device_t:s0 tclass=chr_file type=SYSCALL msg=audit(1369167428.570:531): arch=i386 syscall=mmap2 success=no exit=EACCES a0=0 a1=2000 a2=7 a3=2 items=0 ppid=3690 pid=3775 auid=0 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 ses=2 tty=(none) comm=evince-thumbnai exe=/usr/bin/evince-thumbnailer subj=unconfined_u:unconfined_r:thumb_t:s0-s0:c0.c1023 key=(null) Hash: evince-thumbnai,thumb_t,zero_device_t,chr_file,execute audit2allow #============= thumb_t ============== allow thumb_t zero_device_t:chr_file execute; audit2allow -R require { type thumb_t; } #============= thumb_t ============== dev_rwx_zero(thumb_t) Additional info: reporter: libreport-2.1.4 hashmarkername: setroubleshoot kernel: 3.9.2-200.fc18.i686 type: libreport
