Description of problem: Firefox crashes when logged in as xguest Firefox tries to execute memory (execmem) Version-Release number of selected component (if applicable): rpm -qa xguest xguest-1.0.7-5.fc11.noarch rpm -qa selinux* selinux-policy-3.6.12-72.fc11.noarch selinux-policy-targeted-3.6.12-72.fc11.noarch rpm -qa firefox* firefox-3.5.2-2.fc11.i586 uname -r 2.6.29.6-217.2.8.fc11.i686.PAE How reproducible: always Steps to Reproduce: 1.install xguest 2.login as xguest 3.try to start firefox Actual results: firefox crashes at startup Expected results: firefox should not crash Additional info: AVC: type=AVC msg=audit(1250580934.287:24730): avc: denied { execmem } for pid=4845 comm="firefox" scontext=xguest_u:xguest_r:mozilla_t:s0 tcontext=xguest_u:xguest_r:mozilla_t:s0 tclass=process getsebool -a|grep execmem allow_execmem --> off setting it to 1 resolves the problem, but this setting would allow execmem also for all other applications. If firefox really neads execmem this should be added to the policy. ls /usr/lib/mozilla/plugins librhythmbox-itms-detection-plugin.so libtotem-cone-plugin.so libtotem-gmp-plugin.so libtotem-mully-plugin.so libtotem-narrowspace-plugin.so see also: https://www.redhat.com/archives/fedora-selinux-list/2009-August/msg00139.html thanks, Christoph
