Today the security team will be releasing a GLSA for bug 93558 which is about a faulty package that installs python files as mode 777 which means it was most likely packaged on a windows host. We had a short talk on #-security and decided it would be best to catch these types of bugs early on.
Created attachment 60734 [details, diff] ebuild-warn-world-write.patch Patch also removes the UNSAFE bits from the suid apps.
Fixed on or before 2.0.51.22-r1
Looking through the batch of bugs, I'm not sure that some of these are actually fixed in stable. Others, the requirements have possibly changed after the initial fix was committed. If you think this bug has been closed incorrectly, please reopen or ask that it be reopened.
