Looks like firefox is trying to ptrace one of its plugins, we should allow it unless the user turns on deny_ptrace. 671df206c6c85a6a222809e5bf7b5ab8242a2d80 fixes this in git. selinux-policy-3.12.1-69.fc19 has been submitted as an update for Fedora 19. https://admin.fedoraproject.org/updates/selinux-policy-3.12.1-69.fc19 Package selinux-policy-3.12.1-69.fc19: * should fix your issue, * was pushed to the Fedora 19 testing repository, * should be available at your local mirror within two days.

Description of problem: I'm not certain when this happened. It's backdated. Given the relationship of the labels, I suspect the access was legitimate, but maybe this is something that should be fixed in firefox and not SELinux policy? SELinux is preventing /usr/lib64/firefox/firefox (deleted) from using the 'ptrace' accesses on a process. ***** Plugin catchall (100. confidence) suggests *************************** If you believe that firefox (deleted) should be allowed ptrace access on processes labeled mozilla_plugin_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 firefox /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context staff_u:staff_r:staff_t:s0-s0:c0.c1023 Target Context staff_u:staff_r:mozilla_plugin_t:s0-s0:c0.c1023 Target Objects [ process ] Source firefox Source Path /usr/lib64/firefox/firefox (deleted) Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.11.1-96.fc18.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 3.9.4-200.fc18.x86_64 #1 SMP Fri May 24 20:10:49 UTC 2013 x86_64 x86_64 Alert Count 1 First Seen 2013-06-17 15:37:17 EDT Last Seen 2013-06-17 15:37:17 EDT Local ID 656f3a69-6ed5-48ed-bc1a-a8773352d602 Raw Audit Messages type=AVC msg=audit(1371497837.555:48941): avc: denied { ptrace } for pid=2402 comm="firefox" scontext=staff_u:staff_r:staff_t:s0-s0:c0.c1023 tcontext=staff_u:staff_r:mozilla_plugin_t:s0-s0:c0.c1023 tclass=process type=SYSCALL msg=audit(1371497837.555:48941): arch=x86_64 syscall=ptrace success=no exit=EACCES a0=10 a1=27cf a2=0 a3=0 items=0 ppid=2107 pid=2402 auid=11892 uid=11892 gid=11892 euid=11892 suid=11892 fsuid=11892 egid=11892 sgid=11892 fsgid=11892 ses=18 tty=(none) comm=firefox exe=2F7573722F6C696236342F66697265666F782F66697265666F78202864656C6574656429 subj=staff_u:staff_r:staff_t:s0-s0:c0.c1023 key=(null) Hash: firefox,staff_t,mozilla_plugin_t,process,ptrace Additional info: reporter: libreport-2.1.5 hashmarkername: setroubleshoot kernel: 3.9.8-300.fc19.x86_64 type: libreport
