sshd config file
I'm not sure it matters for reproducing the bug, but here is the sshd config file in use.
This looks like someone is doing some bash redirection around this script which is causing the problem. It can safely be ignored. Something like. sh << _EOF sshkeygen _EOF This package has changed ownership in the Fedora Package Database. Reassigning to the new owner of this component. This message is a notice that Fedora 14 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 14. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At this time, all open bugs with a Fedora 'version' of '14' have been closed as WONTFIX. (Please note: Our normal process is to give advanced warning of this occurring, but we forgot to do that. A thousand apologies.) Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, feel free to reopen this bug and simply change the 'version' to a later Fedora version. Bug Reporter: Thank you for reporting this issue and we are sorry that we were unable to fix it before Fedora 14 reached 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 to click on "Clone This Bug" (top right of this page) and open it against that version of Fedora. 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. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping |
Description of problem: SELinux is preventing /usr/bin/ssh-keygen from write access on the file /tmp/sh-thd-1303119653. ***** Plugin leaks (50.5 confidence) suggests ****************************** If you want to ignore ssh-keygen trying to write access the sh-thd-1303119653 file, because you believe it should not need this access. Then you should report this as a bug. You can generate a local policy module to dontaudit this access. Do # grep /usr/bin/ssh-keygen /var/log/audit/audit.log | audit2allow -D -M mypol # semodule -i mypol.pp ***** Plugin catchall (50.5 confidence) suggests *************************** If you believe that ssh-keygen should be allowed write access on the sh-thd-1303119653 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 ssh-keygen /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:ssh_keygen_t:s0 Target Context system_u:object_r:initrc_tmp_t:s0 Target Objects /tmp/sh-thd-1303119653 [ file ] Source ssh-keygen Source Path /usr/bin/ssh-keygen Port <Unknown> Host arbol.wsrcc.com Source RPM Packages openssh-5.5p1-24.fc14.2 Target RPM Packages Policy RPM selinux-policy-3.9.7-37.fc14 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name arbol.wsrcc.com Platform Linux arbol.wsrcc.com 2.6.35.12-88.fc14.x86_64 #1 SMP Thu Mar 31 21:21:57 UTC 2011 x86_64 x86_64 Alert Count 8 First Seen Mon 11 Apr 2011 07:56:06 AM PDT Last Seen Mon 18 Apr 2011 03:52:30 AM PDT Local ID a3fc341e-5b6e-4291-9117-55783f653168 Raw Audit Messages type=AVC msg=audit(1303123950.376:13): avc: denied { write } for pid=2601 comm="ssh-keygen" path="/tmp/sh-thd-1303119653" dev=tmpfs ino=17160 scontext=system_u:system_r:ssh_keygen_t:s0 tcontext=system_u:object_r:initrc_tmp_t:s0 tclass=file type=SYSCALL msg=audit(1303123950.376:13): arch=x86_64 syscall=execve success=yes exit=0 a0=1c1aa00 a1=1c1b2a0 a2=1c1cfb0 a3=8 items=0 ppid=2600 pid=2601 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm=ssh-keygen exe=/usr/bin/ssh-keygen subj=system_u:system_r:ssh_keygen_t:s0 key=(null) Hash: ssh-keygen,ssh_keygen_t,initrc_tmp_t,file,write audit2allow #============= ssh_keygen_t ============== allow ssh_keygen_t initrc_tmp_t:file write; audit2allow -R #============= ssh_keygen_t ============== allow ssh_keygen_t initrc_tmp_t:file write; Version-Release number of selected component (if applicable): selinux-policy-3.9.7-37.fc14 How reproducible: I'm guessing all the time. Steps to Reproduce: 1. Enable sshd and reboot 2. 3. Actual results: Selinux blocks something sshd thinks it needs. Expected results: Selinux shouldn't block anything sshd thinks it needs.
