Summary: SELinux is preventing /bin/bash access to a leaked /bin/sh file descriptor. Detailed Description: [sh has a permissive type (boinc_project_t). This access was not denied.] SELinux denied access requested by the sh command. It looks like this is either a leaked descriptor or sh output was redirected to a file it is not allowed to access. Leaks usually can be ignored since SELinux is just closing the leak and reporting the error. The application does not use the descriptor, so it will run properly. If this is a redirection, you will not get output in the /bin/sh. You should generate a bugzilla on selinux-policy, and it will get routed to the appropriate package. You can safely ignore this avc. Allowing Access: You can generate a local policy module to allow this access - see FAQ (http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Additional Information: Source Context system_u:system_r:boinc_project_t:s0 Target Context system_u:object_r:bin_t:s0 Target Objects /bin/sh [ lnk_file ] Source sh Source Path /bin/bash Port <Unknown> Host (removed) Source RPM Packages bash-4.1.7-1.fc13 Target RPM Packages bash-4.1.7-1.fc13 Policy RPM selinux-policy-3.7.19-47.fc13 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Plugin Name leaks Host Name (removed) Platform Linux (removed) 2.6.33.6-147.2.4.fc13.x86_64 #1 SMP Fri Jul 23 17:14:44 UTC 2010 x86_64 x86_64 Alert Count 4 First Seen Sat 21 Aug 2010 09:24:34 PM EDT Last Seen Sat 21 Aug 2010 09:24:34 PM EDT Local ID 8eca93ef-9534-410d-940a-3fd92254b8d4 Line Numbers Raw Audit Messages node=(removed) type=AVC msg=audit(1282440274.769:47322): avc: denied { read } for pid=11465 comm="unzip_cpufeat" name="sh" dev=dm-4 ino=1054084 scontext=system_u:system_r:boinc_project_t:s0 tcontext=system_u:object_r:bin_t:s0 tclass=lnk_file node=(removed) type=AVC msg=audit(1282440274.769:47322): avc: denied { execute } for pid=11465 comm="unzip_cpufeat" name="bash" dev=dm-4 ino=1049138 scontext=system_u:system_r:boinc_project_t:s0 tcontext=system_u:object_r:shell_exec_t:s0 tclass=file node=(removed) type=AVC msg=audit(1282440274.769:47322): avc: denied { read open } for pid=11465 comm="unzip_cpufeat" name="bash" dev=dm-4 ino=1049138 scontext=system_u:system_r:boinc_project_t:s0 tcontext=system_u:object_r:shell_exec_t:s0 tclass=file node=(removed) type=AVC msg=audit(1282440274.769:47322): avc: denied { execute_no_trans } for pid=11465 comm="unzip_cpufeat" path="/bin/bash" dev=dm-4 ino=1049138 scontext=system_u:system_r:boinc_project_t:s0 tcontext=system_u:object_r:shell_exec_t:s0 tclass=file node=(removed) type=SYSCALL msg=audit(1282440274.769:47322): arch=c000003e syscall=59 success=yes exit=0 a0=46fe9b a1=7fffeecf4490 a2=7fffeecf57d0 a3=8 items=0 ppid=11464 pid=11465 auid=4294967295 uid=491 gid=472 euid=491 suid=491 fsuid=491 egid=472 sgid=472 fsgid=472 tty=(none) ses=4294967295 comm="sh" exe="/bin/bash" subj=system_u:system_r:boinc_project_t:s0 key=(null) Hash String generated from leaks,sh,boinc_project_t,bin_t,lnk_file,read audit2allow suggests: #============= boinc_project_t ============== allow boinc_project_t bin_t:lnk_file read; allow boinc_project_t shell_exec_t:file { read execute open execute_no_trans };
