The following was filed automatically by setroubleshoot: Summary: SELinux is preventing /usr/lib64/chromium-browser/chromium-browser "execmem" access on <Unknown>. Detailed Description: [SELinux is in permissive mode. This access was not denied.] SELinux denied access requested by chromium-browse. The current boolean settings do not allow this access. If you have not setup chromium-browse to require this access this may signal an intrusion attempt. If you do intend this access you need to change the booleans on this system to allow the access. Allowing Access: One of the following booleans is set incorrectly: allow_execstack, allow_execmem Fix Command: Choose one of the following to allow access: Allow unconfined executables to make their stack executable. This should never, ever be necessary. Probably indicates a badly coded executable, but could indicate an attack. This executable should be reported in bugzilla") # setsebool -P allow_execstack 1 Allow unconfined executables to map a memory region as both executable and writable, this is dangerous and the executable should be reported in bugzilla") # setsebool -P allow_execmem 1 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 chromium-browse Source Path /usr/lib64/chromium-browser/chromium-browser Port <Unknown> Host (removed) Source RPM Packages chromium-4.0.212.0-0.1.20090916svn26424.fc12 Target RPM Packages Policy RPM selinux-policy-3.6.32-12.fc12 Selinux Enabled True Policy Type targeted MLS Enabled True Enforcing Mode Permissive Plugin Name catchall_boolean Host Name (removed) Platform Linux (removed) 2.6.31.1-56.fc12.x86_64 #1 SMP Tue Sep 29 16:16:22 EDT 2009 x86_64 x86_64 Alert Count 21 First Seen Wed 30 Sep 2009 08:08:47 PM EDT Last Seen Thu 01 Oct 2009 05:25:54 PM EDT Local ID aebee153-ed0a-4507-9f9c-05039e81de63 Line Numbers Raw Audit Messages node=(removed) type=AVC msg=audit(1254432354.347:51): avc: denied { execmem } for pid=3839 comm="chromium-browse" 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(1254432354.347:51): arch=c000003e syscall=9 success=yes exit=139679631908864 a0=0 a1=40000 a2=7 a3=22 items=0 ppid=1 pid=3839 auid=500 uid=500 gid=500 euid=500 suid=500 fsuid=500 egid=500 sgid=500 fsgid=500 tty=(none) ses=2 comm="chromium-browse" exe="/usr/lib64/chromium-browser/chromium-browser" subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 key=(null) Hash String generated from selinux-policy-3.6.32-12.fc12,catchall_boolean,chromium-browse,unconfined_t,unconfined_t,process,execmem audit2allow suggests: #============= unconfined_t ============== allow unconfined_t self:process execmem;
