The GeoIP C API is an open source library (LGPL) for MaxMind's GeoIP data products. GeoIP-1.4.7.tar.gz (the latest version) contains a directory traversal weakness whereby a remote malicious update server (responding to requests at updates.maxmind.com) may overwrite arbitrary files. apps/geoipupdate.c, added a sanity check in 1.4.1 but does not handle Windows paths containing backslash or colon. apps/geoipupdate-pureperl.pl, introduced in 1.4.5, does not filter any filenames returned by the remote server. The fix is to reject invalid filenames, e.g., leading '.', or containing slash, backslash (Windows), or colons (Windows).
