SELinux is preventing /opt/TweetDeck/bin/TweetDeck from using the 'execstack' accesses on a process. ***** Plugin allow_execstack (53.1 confidence) suggests ******************** If you do not think /opt/TweetDeck/bin/TweetDeck should need to map stack memory that is both writable and executable. Then you need to report a bug. This is a potentially dangerous access. Do contact your security administrator and report this issue. ***** Plugin catchall_boolean (42.6 confidence) suggests ******************* If you want to 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 Then you must tell SELinux about this by enabling the 'allow_execstack' boolean. Do setsebool -P allow_execstack 1 ***** Plugin catchall (5.76 confidence) suggests *************************** If you believe that TweetDeck should be allowed execstack access on processes labeled unconfined_t by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # grep TweetDeck /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp 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 Unknown [ process ] Source TweetDeck Source Path /opt/TweetDeck/bin/TweetDeck Port <Unknown> Host (removed) Source RPM Packages nautilus-2.32.2.1-1.fc14 Target RPM Packages Policy RPM selinux-policy-3.9.7-19.fc14 Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name (removed) Platform Linux (removed) 2.6.35.10-72.fc14.i686 #1 SMP Mon Dec 20 22:05:49 UTC 2010 i686 i686 Alert Count 17 First Seen Fri 24 Dec 2010 02:38:28 AM EET Last Seen Sun 16 Jan 2011 08:17:32 PM EET Local ID ff59ad11-05e6-4746-a704-5ec2eda0df5d Raw Audit Messages type=AVC msg=audit(1295201852.682:34103): avc: denied { execstack } for pid=3849 comm="nautilus" scontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tcontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tclass=process TweetDeck,unconfined_t,unconfined_t,process,execstack type=SYSCALL msg=audit(1295201852.682:34103): arch=i386 syscall=mprotect success=yes exit=0 a0=bfdac000 a1=1000 a2=1000007 a3=bfdab0ec items=0 ppid=3676 pid=3849 auid=500 uid=500 gid=500 euid=500 suid=500 fsuid=500 egid=500 sgid=500 fsgid=500 tty=(none) ses=1 comm=nautilus exe=/usr/bin/nautilus subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 key=(null) TweetDeck,unconfined_t,unconfined_t,process,execstack #============= unconfined_t ============== #!!!!
