Description Troels Arvin 2017-08-02 03:44:45 EDT
Description of problem:
After upgrading from Fedora 25 to Fedora 26, akregator would no longer start:

$ akregator
akregator: error while loading shared libraries: libQt5WebEngineCore.so.5: cannot enable executable stack as shared object requires: Permission denied

Meanwhile, in /var/log/audit/audit.log:

type=AVC msg=audit(1501659590.197:793): avc:  denied  { execstack } for  pid=20267 comm="akregator" scontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tcontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023 tclass=process permissive=0

Workaround: As root, I ran 
execstack -c /usr/lib64/libQt5WebEngineCore.so.5

After that:
# execstack -q /usr/lib64/libQt5WebEngineCore.so.5
- /usr/lib64/libQt5WebEngineCore.so.5

And now, Akregator would run. But now, my qt5-qtwebengine package is no longer unmodified:
$ rpm --verify qt5-qtwebengine
SM5....T.    /usr/lib64/libQt5WebEngineCore.so.5

I don't know if this is a problem in the qt5-qtwebengine package, or if it's a problem with Akregator.
