Summary: SELinux is preventing /usr/bin/ksudoku "execmem" access on <Unknown>. Detailed Description: [SELinux is in permissive mode. This access was not denied.] SELinux denied access requested by ksudoku. The current boolean settings do not allow this access. If you have not setup ksudoku 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 amarok Source Path /usr/bin/amarok Port <Unknown> Host (removed) Source RPM Packages kdegames-4.3.2-1.fc12 Target RPM Packages Policy RPM selinux-policy-3.6.32-24.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 5 First Seen Mon 12 Oct 2009 12:09:44 PM CEST Last Seen Tue 13 Oct 2009 10:35:58 PM CEST Local ID 1e36d8ae-4cf4-4d2f-b1e3-373b7e68859f Line Numbers Raw Audit Messages node=(removed) type=AVC msg=audit(1255466158.480:87): avc: denied { execmem } for pid=13608 comm="ksudoku" 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(1255466158.480:87): arch=c000003e syscall=9 success=yes exit=230336118784 a0=35a11a4000 a1=3d000 a2=7 a3=812 items=0 ppid=1596 pid=13608 auid=500 uid=500 gid=500 euid=500 suid=500 fsuid=500 egid=500 sgid=500 fsgid=500 tty=(none) ses=1 comm="ksudoku" exe="/usr/bin/ksudoku" subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 key=(null) Hash String generated from selinux-policy-3.6.32-24.fc12,catchall_boolean,amarok,unconfined_t,unconfined_t,process,execmem audit2allow suggests: #============= unconfined_t ============== allow unconfined_t self:process execmem;
Hi, I've reported this denial because there seems to be two - totally - independent applications involved.ksudoku is a game and amarok a multimedia app. Is there a logical explanation for this 'relationship'? Martin Kho
Did you previously get an AVC on amarok? This looks like a bug in setroubleshoot? Which app actually generated the AVC?
Hi, Found the cause of my AVC's. I was trying/testing the nvidia beta propriety driver. This generated all sort of AVC's. Now I'am running nouveau again and get no errors. Sorry for the noise :-X Martin Kho
Ok if you want to use the nvidia driver you need to set the boolean allow_execmem. setsebool -P allow_execmem 1
Hi, Thanks for the tip. But i like to run the open source nouveau driver :-) Martin kho
I am not a big fan of closed source anything. :^)
