The following was filed automatically by setroubleshoot: Summary: SELinux is preventing /usr/bin/desktop-effects "execmem" access on <Unknown>. Detailed Description: [desktop-effects has a permissive type (unconfined_t). This access was not denied.] SELinux denied access requested by desktop-effects. The current boolean settings do not allow this access. If you have not setup desktop-effects 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 desktop-effects Source Path /usr/bin/desktop-effects Port <Unknown> Host (removed) Source RPM Packages desktop-effects-0.8.4-2.fc12 Target RPM Packages Policy RPM selinux-policy-3.6.32-12.fc12 Selinux Enabled True Policy Type targeted MLS Enabled True Enforcing Mode Enforcing 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 3 First Seen Mon 28 Sep 2009 05:40:33 PM CEST Last Seen Tue 06 Oct 2009 12:02:05 AM CEST Local ID 61cc5814-766a-4aad-9bde-9022c603cf9e Line Numbers Raw Audit Messages node=(removed) type=AVC msg=audit(1254780125.911:53): avc: denied { execmem } for pid=2863 comm="desktop-effects" 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(1254780125.911:53): arch=c000003e syscall=10 success=yes exit=0 a0=3e3cc20000 a1=87c a2=7 a3=3e3cc02858 items=0 ppid=1 pid=2863 auid=500 uid=500 gid=500 euid=500 suid=500 fsuid=500 egid=500 sgid=500 fsgid=500 tty=(none) ses=2 comm="desktop-effects" exe="/usr/bin/desktop-effects" 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,desktop-effects,unconfined_t,unconfined_t,process,execmem audit2allow suggests: #============= unconfined_t ============== allow unconfined_t self:process execmem;
desktop-effects should not need this, although it might be caused by nvidia drivers?
desktop-effects links to libGL in order to check if 3D capabilities are available before trying to launch a 3D compositor. Other than that, it's just a standard GTK+ application. I have no idea how that interacts with execmem
I would figure this is something to do with third party libraries.
Fredrik turn on the allow_execmem boolean for now. setsebool -P allow_exemem 1
This bug appears to have been reported against 'rawhide' during the Fedora 12 development cycle. Changing version to '12'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
This message is a reminder that Fedora 12 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 12. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '12'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 12's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 12 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 12 changed to end-of-life (EOL) status on 2010-12-02. Fedora 12 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
