Summary: SELinux is preventing /usr/lib/nspluginwrapper/plugin-config from making the program stack executable. Detailed Description: The plugin-config 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 plugin-config 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. 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 plugin-config to run correctly, you can change the context of the executable to execmem_exec_t. "chcon -t execmem_exec_t '/usr/lib/nspluginwrapper/plugin-config'" 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 execmem_exec_t '/usr/lib/nspluginwrapper/plugin-config'" Fix Command: chcon -t execmem_exec_t '/usr/lib/nspluginwrapper/plugin-config' Additional Information: Source Context unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1 023 Target Context unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1 023 Target Objects None [ process ] Source plugin-config Source Path /usr/lib/nspluginwrapper/plugin-config Port <Unknown> Host (removed) Source RPM Packages nspluginwrapper-1.3.0-8.fc12 Target RPM Packages Policy RPM selinux-policy-3.6.32-114.fc12 Selinux Enabled True Policy Type targeted MLS Enabled True Enforcing Mode Enforcing Plugin Name allow_execstack Host Name (removed) Platform Linux (removed) 2.6.31.5-127.fc12.i686 #1 SMP Sat Nov 7 21:41:45 EST 2009 i686 i686 Alert Count 194 First Seen Mon 01 Mar 2010 11:42:49 PM CST Last Seen Sun 09 May 2010 09:36:22 PM CDT Local ID 96443ed7-0b6f-41dd-acad-ff9ac7b8dc7b Line Numbers Raw Audit Messages node=(removed) type=AVC msg=audit(1273458982.639:15): avc: denied { execstack } for pid=1935 comm="plugin-config" scontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tcontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tclass=process node=(removed) type=SYSCALL msg=audit(1273458982.639:15): arch=40000003 syscall=125 success=no exit=-13 a0=bfdc3000 a1=1000 a2=1000007 a3=bfdbad40 items=0 ppid=1933 pid=1935 auid=500 uid=500 gid=500 euid=0 suid=0 fsuid=0 egid=500 sgid=500 fsgid=500 tty=(none) ses=1 comm="plugin-config" exe="/usr/lib/nspluginwrapper/plugin-config" subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 key=(null) Hash String generated from selinux-policy-3.6.32-114.fc12,allow_execstack,plugin-config,unconfined_t,unconfined_t,process,execstack audit2allow suggests:/usr/lib/python2.6/site-packages/ABRTUtils.so: undefined symbol: _ZN10CDebugDump6CreateERKSsx #============= unconfined_t ============== allow unconfined_t self:process execstack;
Could you make sure your policy was successfully installed. Execute yum reinstall selinux-policy-targeted And make sure nothing breaks on the install.
