This is an Adobe AIR application distributed by US cable provider Comcast. The suggested fix ... # grep 436F6D6361737420556E6976657273 /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp resolved the avc for me. Thanks! *** This bug has been marked as a duplicate of bug 652297 *** |
SELinux is preventing /opt/Comcast Universal Caller ID/bin/Comcast Universal Caller ID from using the 'execstack' accesses on a process. ***** Plugin allow_execstack (53.1 confidence) suggests ******************** If you believe that None should not require execstack Then you should clear the execstack flag and see if /opt/Comcast Universal Caller ID/bin/Comcast Universal Caller ID works correctly. Report this as a bug on None. You can clear the exestack flag by executing: Do execstack -c None ***** 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 Comcast Universal Caller ID 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 436F6D6361737420556E6976657273 /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 436F6D6361737420556E6976657273 Source Path /opt/Comcast Universal Caller ID/bin/Comcast Universal Caller ID Port <Unknown> Host (removed) Source RPM Packages com.comcast.callerid.13a1fa90f0fc9dc009fb0956add0f 13f8608561b.1-ComcastCallerID2.1.7-1 Target RPM Packages Policy RPM selinux-policy-3.9.7-29.fc14 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 2.6.35.11-83.fc14.i686 #1 SMP Mon Feb 7 07:04:18 UTC 2011 i686 i686 Alert Count 2 First Seen Thu 10 Feb 2011 08:28:18 PM CST Last Seen Wed 16 Feb 2011 02:06:00 PM CST Local ID 62101fd6-b7e1-48e4-b190-821b8c29c686 Raw Audit Messages type=AVC msg=audit(1297886760.355:21723): avc: denied { execstack } for pid=10274 comm=436F6D6361737420556E6976657273 scontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tcontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tclass=process type=SYSCALL msg=audit(1297886760.355:21723): arch=i386 syscall=mprotect success=no exit=EACCES a0=bfb18000 a1=1000 a2=1000007 a3=bfb16db4 items=0 ppid=2840 pid=10274 auid=500 uid=500 gid=500 euid=500 suid=500 fsuid=500 egid=500 sgid=500 fsgid=500 tty=(none) ses=4 comm=436F6D6361737420556E6976657273 exe=2F6F70742F436F6D6361737420556E6976657273616C2043616C6C65722049442F62696E2F436F6D6361737420556E6976657273616C2043616C6C6572204944 subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 key=(null) Hash: 436F6D6361737420556E6976657273,unconfined_t,unconfined_t,process,execstack audit2allow #============= unconfined_t ============== #!!!!
