Dear all, After applying the fix suggested by Mr. Walsh, [root@localhost ~]# setsebool -P allow_unconfined_nsplugin_transition=1 allow_nsplugin_execmem=1 [root@localhost ~]# getsebool -a | grep nsp allow_nsplugin_execmem --> on allow_unconfined_nsplugin_transition --> on Seamonkey is asking permission for the stack. I do not want to allow access if it is not correct for seamonkey to allow stack execution. Please help me nail this one as well and crossing my fingers that firefox/minefield does not ask as well. Summary: SELinux is preventing seamonkey-bin from making the program stack executable. Detailed Description: The seamonkey-bin application attempted to make its stack executable. This is a potential security problem. This should never ever be necessary. Stack memory is not executable on most OSes these days and this will not change. Executable stack memory is one of the biggest security problems. An execstack error might in fact be most likely raised by malicious code. Applications are sometimes coded incorrectly and request this permission. The SELinux Memory Protection Tests (http://people.redhat.com/drepper/selinux-mem.html) web page explains how to remove this requirement. If seamonkey-bin does not work and you need it to work, you can configure SELinux temporarily to allow this access until the application is fixed. Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this package. Allowing Access: Sometimes a library is accidentally marked with the execstack flag, if you find a library with this flag you can clear it with the execstack -c LIBRARY_PATH. Then retry your application. If the app continues to not work, you can turn the flag back on with execstack -s LIBRARY_PATH. Otherwise, if you trust seamonkey-bin to run correctly, you can change the context of the executable to unconfined_execmem_exec_t. "chcon -t unconfined_execmem_exec_t '/usr/lib/seamonkey-1.1.8/seamonkey-bin'" You must also change the default file context files on the system in order to preserve them even on a full relabel. "semanage fcontext -a -t unconfined_execmem_exec_t '/usr/lib/seamonkey-1.1.8/seamonkey-bin'" Fix Command: chcon -t unconfined_execmem_exec_t '/usr/lib/seamonkey-1.1.8/seamonkey-bin' Additional Information: Source Context unconfined_u:unconfined_r:unconfined_t:SystemLow- SystemHigh Target Context unconfined_u:unconfined_r:unconfined_t:SystemLow- SystemHigh Target Objects None [ process ] Source firefox Source Path /usr/lib/firefox-3.0b3pre/firefox Port <Unknown> Host localhost Source RPM Packages seamonkey-1.1.8-4.fc9 Target RPM Packages Policy RPM selinux-policy-3.3.0-1.fc9 Selinux Enabled True Policy Type targeted MLS Enabled True Enforcing Mode Enforcing Plugin Name allow_execstack Host Name localhost Platform Linux localhost 2.6.25-0.65.rc2.git7.fc9 #1 SMP Sat Feb 23 23:06:09 EST 2008 i686 athlon Alert Count 140 First Seen Fri 01 Feb 2008 05:08:54 PM CST Last Seen Tue 26 Feb 2008 03:17:04 PM CST Local ID c4806f30-a6dc-43b0-8901-5531075795f7 Line Numbers Raw Audit Messages host=localhost type=AVC msg=audit(1204060624.602:108): avc: denied { execstack } for pid=20290 comm="seamonkey-bin" scontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tcontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tclass=process host=localhost type=SYSCALL msg=audit(1204060624.602:108): arch=40000003 syscall=125 success=no exit=-13 a0=bfc72000 a1=1000 a2=1000007 a3=fffff000 items=0 ppid=1 pid=20290 auid=500 uid=500 gid=500 euid=500 suid=500 fsuid=500 egid=500 sgid=500 fsgid=500 tty=(none) ses=1 comm="seamonkey-bin" exe="/usr/lib/seamonkey-1.1.8/seamonkey-bin" subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 key=(null) ____________________________________________________________________________________ Looking for last minute shopping deals?
