CESA-2005:771: wget security update



Updated wget package that fixes several security issues is now available. This update has been rated as having low security impact by the CentOS Security Response Team.

GNU Wget is a file retrieval utility that can use either the HTTP or FTP protocols. A bug was found in the way wget writes files to the local disk. If a malicious local user has write access to the directory wget is saving a file into, it is possible to overwrite files that the user running wget has write access to. (CAN-2004-2014) A bug was found in the way wget filters redirection URLs. It is possible for a malicious Web server to overwrite files the user running wget has write access to. Note: in order for this attack to succeed the local DNS would need to resolve ".." to an IP address, which is an unlikely situation. (CAN-2004-1487) A bug was found in the way wget displays HTTP response codes. It is possible that a malicious web server could inject a specially crafted terminal escape sequence capable of misleading the user running wget. (CAN-2004-1488) Users should upgrade to this updated package, which contains a version of wget that is not vulnerable to these issues.
