DESCRIPTION:
Javier Fernández-Sanguino Peña has reported a vulnerability in
Docbook-to-Man, which can be exploited by malicious, local users to
perform certain actions on a vulnerable system with escalated
privileges.

The vulnerability is caused due to the docbook-to-man.sh script
creating temporary files insecurely. This can be exploited via
symlink attacks to overwrite arbitrary files with the privileges of
the user running the vulnerable script.

SOLUTION:
Grant only trusted users access to affected systems.
