restorecon -R -v /usr/local/lib/ Should fix the context. Whatever installed these files did not set the proper context. |
Description of problem: Executing a program (openCanvas 11b72rv1) under wine, results in the following selinux error: """ Summary SELinux is preventing wine-pthread from loading /usr/local/lib/wine/kernel32.dll.so which requires text relocation. Detailed Description The wine-pthread application attempted to load /usr/local/lib/wine/kernel32.dll.so which requires text relocation. This is a potential security problem. Most libraries do not need this permission. Libraries are sometimes coded incorrectly and request this permission. The http://people.redhat.com/drepper/selinux-mem.html web page explains how to remove this requirement. You can configure SELinux temporarily to allow /usr/local/lib/wine/kernel32.dll.so to use relocation as a workaround, until the library is fixed. Please file a http://bugzilla.redhat.com/bugzilla/enter_bug.cgi against this package. Allowing Access If you trust /usr/local/lib/wine/kernel32.dll.so to run correctly, you can change the file context to textrel_shlib_t. "chcon -t textrel_shlib_t /usr/local/lib/wine/kernel32.dll.so" 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 textrel_shlib_t /usr/local/lib/wine/kernel32.dll.so" The following command will allow this access: chcon -t textrel_shlib_t /usr/local/lib/wine/kernel32.dll.so Additional Information Source Context system_u:system_r:unconfined_t:s0 Target Context system_u:object_r:lib_t:s0 Target Objects /usr/local/lib/wine/kernel32.dll.so [ file ] Affected RPM Packages Policy RPM selinux-policy-3.0.8-56.fc8 Selinux Enabled True Policy Type targeted MLS Enabled True Enforcing Mode Permissive Plugin Name plugins.allow_execmod Host Name mireille Platform Linux mireille 2.6.23.1-49.fc8 #1 SMP Thu Nov 8 21:41:26 EST 2007 i686 i686 Alert Count 1 First Seen Mon 26 Nov 2007 11:12:01 AM PST Last Seen Mon 26 Nov 2007 11:12:01 AM PST Local ID 6bf0b6bc-269a-44fc-b41f-6854ff6ddfdf Line Numbers Raw Audit Messages avc: denied { execmod } for comm=wine-pthread dev=sda9 path=/usr/local/lib/wine/kernel32.dll.so pid=4005 scontext=system_u:system_r:unconfined_t:s0 tclass=file tcontext=system_u:object_r:lib_t:s0 """ Version-Release number of selected component (if applicable): selinux-policy-targeted 3.0.8-56
