"Recently, Trustix Secure Linux discovered a vulnerability in the
postgresql-contrib package. The script 'make_oidjoins_check' created
temporary files in an insecure way, which allowed a symlink attack to
create or overwrite arbitrary files with the privileges of the user
invoking the script.

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
