pt_chown in the glibc package prior to 2.19-18+deb8u4 on Debian jessie; the elibc package prior to 2.15-0ubuntu10.14 on Ubuntu 12.04 LTS and prior to 2.19-0ubuntu6.8 on Ubuntu 14.04 LTS; and the glibc package prior to 2.21-0ubuntu4.2 on Ubuntu 15.10 and prior to 2.23-0ubuntu1 on Ubuntu 16.04 LTS and 16.10 lacks a namespace check associated with file-descriptor passing, which allows local users to capture keystrokes and spoof data, and possibly gain privileges, via pts read and write operations, related to debian/sysdeps/linux.mk. NOTE: this is not considered a vulnerability in the upstream GNU C Library because the upstream documentation has a clear security recommendation against the --enable-pt_chown option.
