Mozilla Firefox is an open source Web browser.
Several cross-site scripting (XSS) flaws were found in the way Firefox processed certain malformed web pages. A malicious web page could display misleading information which may result in a user unknowingly divulging sensitive information such as a password. (CVE-2006-6077, CVE-2007-0995, CVE-2007-0996)
A flaw was found in the way Firefox cached web pages on the local disk. A malicious web page may be able to inject arbitrary HTML into a browsing session if the user reloads a targeted site. (CVE-2007-0778)
A flaw was found in the way Firefox displayed certain web content. A malicious web page could generate content which could overlay user interface elements such as the hostname and security indicators, tricking a user into thinking they are visiting a different site. (CVE-2007-0779)
Two flaws were found in the way Firefox displayed blocked popup windows. If a user can be convinced to open a blocked popup, it is possible to read arbitrary local files, or conduct an XSS attack against the user. (CVE-2007-0780, CVE-2007-0800)
Two buffer overflow flaws were found in the Network Security Services (NSS) code for processing the SSLv2 protocol. Connecting to a malicious secure web server could cause the execution of arbitrary code as the user running Firefox. (CVE-2007-0008, CVE-2007-0009)
A flaw was found in the way Firefox handled the "location.hostname" value during certain browser domain checks. This flaw could allow a malicious web site to set domain cookies for an arbitrary site, or possibly perform an XSS attack. (CVE-2007-0981)
Users of Firefox are advised to upgrade to these erratum packages, which contain Firefox version 184.108.40.206 that corrects these issues.
