Description of problem: This is a reappearance of bug 630217, with the same behaviour; Adobe reader does not run because it has components that (allegedly) require an executable stack (libsccore.so and libcrypto.so) and SELinux bars them from running. Supposedly this was fixed in selinux-policy 3.9.7-12.fc14 but it reappears the policy revision below. Version-Release number of selected component (if applicable): selinux-policy-3.9.7-42.fc14 How reproducible: By running Adobe Reader 9 on an selinux-enabled FC14 machine Steps to Reproduce: 1. Update SELinux policy to the version above 2. Enable SELinux (if not already enabled) 3. Install Adobe Reader 9 4. Run Reader 9. Actual results: SELinux prevents execution Expected results: Adobe Reader 9 starts. Additional info: SELinux is preventing /home/amulocal/linux/appl/Acrobat-9.4.2/Adobe/Reader9/Reader/intellinux/bin/acroread from using the execstack access 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 /home/amulocal/linux/appl/Acrobat-9.4.2/Adobe/Reader9/Reader/intellinux/bin/acroread 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 acroread 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 acroread /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 acroread Source Path /home/amulocal/linux/appl/Acrobat-9.4.2/Adobe/Read er9/Reader/intellinux/bin/acroread Port <Unknown> Host footage.cs.man.ac.uk Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.9.7-42.fc14 Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name footage.cs.man.ac.uk Platform Linux footage.cs.man.ac.uk 2.6.35.13-92.fc14.i686.PAE #1 SMP Sat May 21 17:33:09 UTC 2011 i686 i686 Alert Count 3 First Seen Mon 08 Aug 2011 17:19:39 BST Last Seen Wed 10 Aug 2011 17:52:57 BST Local ID 37149a88-262d-4a83-9a5c-16c439392e52 Raw Audit Messages type=AVC msg=audit(1312995177.219:28906): avc: denied { execstack } for pid=28853 comm="acroread" 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(1312995177.219:28906): arch=i386 syscall=mprotect success=no exit=EACCES a0=bf8b5000 a1=1000 a2=1000007 a3=bf8b5728 items=0 ppid=1 pid=28853 auid=21490 uid=21490 gid=800 euid=21490 suid=21490 fsuid=21490 egid=800 sgid=800 fsgid=800 tty=(none) ses=197 comm=acroread exe=/home/amulocal/linux/appl/Acrobat-9.4.2/Adobe/Reader9/Reader/intellinux/bin/acroread subj=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 key=(null) Hash: acroread,unconfined_t,unconfined_t,process,execstack audit2allow #============= unconfined_t ============== #!!!!

You do not have the file installed into the system directory where we would have a chance of fixing this. Installed in your homedir, it is up to you to fix the label or turn off the check. setsebool -P allow_execstack 1
