Description Jaroslav Reznik 2009-10-04 07:59:50 UTC
The following was filed automatically by setroubleshoot:


SELinux is preventing /usr/bin/arora "execmem" access on <Unknown>.

Detailed Description:

[SELinux is in permissive mode. This access was not denied.]

SELinux denied access requested by arora. The current boolean settings do not
allow this access. If you have not setup arora to require this access this may
signal an intrusion attempt. If you do intend this access you need to change the
booleans on this system to allow the access.

Allowing Access:

One of the following booleans is set incorrectly: allow_execstack, allow_execmem

Fix Command:

Choose one of the following to allow access:
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")
# setsebool -P allow_execstack 1
Allow unconfined executables to map a memory region as both executable and
writable, this is dangerous and the executable should be reported in bugzilla")
# setsebool -P allow_execmem 1
