Description:
Debian has issued an update for geneweb. This fixes a vulnerability, 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 maintainer scripts automatically converting files believed to be old ".gwb" database files without checking the file permissions and content. This can be exploited via symlink attacks to manipulate arbitrary files with the privileges of the user running the maintainer scripts.

Solution:
Apply updated packages.
