"Recently, Trustix Secure Linux discovered a vulnerability in the
openssl package. The auxiliary script 'der_chop' created temporary
files in an insecure way, which could allow a symlink attack to create
or overwrite arbitrary files with the privileges of the user invoking
the program.

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."
