SELinux is preventing /usr/lib64/nspluginwrapper/plugin-config from read, write access on the chr_file /dev/ptmx. ***** Plugin leaks (50.5 confidence) suggests ****************************** If you want to ignore plugin-config trying to read write access the ptmx chr_file, because you believe it should not need this access. Then you should report this as a bug. You can generate a local policy module to dontaudit this access. Do # grep /usr/lib64/nspluginwrapper/plugin-config /var/log/audit/audit.log | audit2allow -D -M mypol # semodule -i mypol.pp ***** Plugin catchall (50.5 confidence) suggests *************************** If you believe that plugin-config should be allowed read write access on the ptmx chr_file 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 plugin-config /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context unconfined_u:unconfined_r:nsplugin_config_t:s0-s0: c0.c1023 Target Context system_u:object_r:ptmx_t:s0 Target Objects /dev/ptmx [ chr_file ] Source plugin-config Source Path /usr/lib64/nspluginwrapper/plugin-config Port <Unknown> Host (removed) Source RPM Packages nspluginwrapper-1.3.0-17.fc15 Target RPM Packages Policy RPM selinux-policy-3.9.14-2.fc15 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 2.6.38-0.rc5.git1.1.fc15.x86_64 #1 SMP Thu Feb 17 01:49:02 UTC 2011 x86_64 x86_64 Alert Count 3 First Seen fim 17.feb 2011, 00:53:56 GMT Last Seen lau 19.feb 2011, 10:12:23 GMT Local ID b24a6ecf-885a-48f2-b419-ba705b34c7f7 Raw Audit Messages type=AVC msg=audit(1298110343.250:481): avc: denied { read write } for pid=2198 comm="plugin-config" path="/dev/ptmx" dev=devtmpfs ino=1077 scontext=unconfined_u:unconfined_r:nsplugin_config_t:s0-s0:c0.c1023 tcontext=system_u:object_r:ptmx_t:s0 tclass=chr_file type=SYSCALL msg=audit(1298110343.250:481): arch=x86_64 syscall=execve success=yes exit=0 a0=149a5d0 a1=149a510 a2=149acd0 a3=1 items=0 ppid=2196 pid=2198 auid=500 uid=500 gid=500 euid=0 suid=0 fsuid=0 egid=500 sgid=500 fsgid=500 tty=(none) ses=2 comm=plugin-config exe=/usr/lib64/nspluginwrapper/plugin-config subj=unconfined_u:unconfined_r:nsplugin_config_t:s0-s0:c0.c1023 key=(null) Hash: plugin-config,nsplugin_config_t,ptmx_t,chr_file,read,write audit2allow #============= nsplugin_config_t ============== allow nsplugin_config_t ptmx_t:chr_file { read write }; audit2allow -R #============= nsplugin_config_t ============== allow nsplugin_config_t ptmx_t:chr_file { read write };
