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.

text-markup, please verify/advise.

We don't have docbook-to-man, we have docbook2man as part of docbook-sgml-utils. AFAICT it isn't affected by this vulnerability.

Closing as INVALID, feel free to reopen if you think I'm wrong.
