Bug ID: 19112
Summary: umask: add fortification checks
Product: glibc
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: vapier at gentoo dot org
Reporter: vapier at gentoo dot org

someone pointed out that bionic has added a fortify check to catch
bad/incorrect values:
https://groups.google.com/d/msg/android-security-discuss/39oaPaWJX2I/I4CsguoRB60J
umask (bionic FORTIFY_SOURCE extension. Detect invalid umask calls. For
example: umask(777) instead of umask(0777))
it should be easy to add that to glibc
