You will need to turn on the boolean. Do you know which cronjob causes this? Is this your own cronjob? |
SELinux is preventing /usr/bin/php from using the 'execstack' accesses on a process. ***** Plugin catchall_boolean (89.3 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 (11.6 confidence) suggests *************************** If you believe that php should be allowed execstack access on processes labeled system_cronjob_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 php /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:system_cronjob_t:s0-s0:c0.c1023 Target Context system_u:system_r:system_cronjob_t:s0-s0:c0.c1023 Target Objects Unknown [ process ] Source php Source Path /usr/bin/php Port <Unknown> Host (removed) Source RPM Packages php-cli-5.3.8-3.fc14 Target RPM Packages Policy RPM selinux-policy-3.9.7-46.fc14 Selinux Enabled True Policy Type targeted Enforcing Mode Permissive Host Name (removed) Platform Linux (removed) 2.6.35.14-106.fc14.i686 #1 SMP Wed Nov 23 13:57:33 UTC 2011 i686 i686 Alert Count 3 First Seen Thu 08 Dec 2011 02:28:00 PM EST Last Seen Thu 08 Dec 2011 02:36:00 PM EST Local ID 9324a144-4c46-472f-935d-af0b1f064a9c Raw Audit Messages type=AVC msg=audit(1323372960.293:48016): avc: denied { execstack } for pid=7678 comm="php" scontext=system_u:system_r:system_cronjob_t:s0-s0:c0.c1023 tcontext=system_u:system_r:system_cronjob_t:s0-s0:c0.c1023 tclass=process type=SYSCALL msg=audit(1323372960.293:48016): arch=i386 syscall=mprotect success=yes exit=0 a0=bfd42000 a1=1000 a2=1000007 a3=bfd41794 items=0 ppid=7676 pid=7678 auid=500 uid=48 gid=48 euid=48 suid=48 fsuid=48 egid=48 sgid=48 fsgid=48 tty=(none) ses=1 comm=php exe=/usr/bin/php subj=system_u:system_r:system_cronjob_t:s0-s0:c0.c1023 key=(null) Hash: php,system_cronjob_t,system_cronjob_t,process,execstack audit2allow #============= system_cronjob_t ============== #!!!!
