Description of problem: SELinux is preventing /usr/bin/perl from 'write, open' accesses on the file /tmp/U0mD08rlUx. ***** Plugin catchall (100. confidence) suggests *************************** If you believe that perl should be allowed write open access on the U0mD08rlUx 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 graph.cgi /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:httpd_collectd_script_t:s0 Target Context system_u:object_r:tmp_t:s0 Target Objects /tmp/U0mD08rlUx [ file ] Source graph.cgi Source Path /usr/bin/perl Port <Unknown> Host clio Source RPM Packages perl-5.16.2-238.fc18.x86_64 Target RPM Packages Policy RPM selinux-policy-3.11.1-81.fc18.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name clio Platform Linux clio 3.7.9-205.fc18.x86_64 #1 SMP Sun Feb 24 20:10:02 UTC 2013 x86_64 x86_64 Alert Count 1 First Seen 2013-03-02 00:38:31 CET Last Seen 2013-03-02 00:38:31 CET Local ID 24e0e4be-e20c-4dd5-b34b-026446d3b2ae Raw Audit Messages type=AVC msg=audit(1362181111.974:2755): avc: denied { write open } for pid=5781 comm="graph.cgi" path="/tmp/U0mD08rlUx" dev="tmpfs" ino=34736 scontext=system_u:system_r:httpd_collectd_script_t:s0 tcontext=system_u:object_r:tmp_t:s0 tclass=file type=SYSCALL msg=audit(1362181111.974:2755): arch=x86_64 syscall=open success=no exit=EACCES a0=7fff8b55dd30 a1=241 a2=1b6 a3=238 items=0 ppid=2714 pid=5781 auid=4294967295 uid=48 gid=48 euid=48 suid=48 fsuid=48 egid=48 sgid=48 fsgid=48 ses=4294967295 tty=(none) comm=graph.cgi exe=/usr/bin/perl subj=system_u:system_r:httpd_collectd_script_t:s0 key=(null) Hash: graph.cgi,httpd_collectd_script_t,tmp_t,file,write,open audit2allow #============= httpd_collectd_script_t ============== #!!!!

It looks like graph.cgi is writing temp files with random names, which audit2allow isn't smart enough to figure out.
