Dean Gaudet has reported a vulnerability in GeoIP, which can be exploited by malicious people to overwrite arbitary files on a user's system.
The "GeoIP_update_database_general()" function does not correctly sanitise the filename returned from the update server. This can be exploited by e.g. a malicious update server via directory traversal attacks to overwrite arbitrary files with the privileges of the user running the update.
The vulnerability is reported in versions prior to 1.4.1.
Solution: Update to version 1.4.1.
