Summary:

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

(I know that Skype is an evil closed-source program, but it would still be nice for it to work out of the box ...)

Detailed Description:

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

SELinux denied access requested by skype. The current boolean settings do not
allow this access. If you have not setup skype 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
