Some vulnerabilities have been reported in Bugzilla, which can be exploited by malicious users to bypass certain security restrictions and by malicious people to conduct HTTP response splitting and cross-site scripting attacks

1) Certain unspecified input is not properly sanitised before being returned to the user. This can be exploited to insert arbitrary HTTP headers, which will be included in a response sent to the user.

2) The application does not properly restrict access to graphs generated by other projects, which can be exploited to access otherwise restricted graphs and product names via a specially crafted URL.

3) Some vulnerabilities are caused by use of a vulnerable version of YUI.
