Mozilla Firefox is an open source Web browser.
Cross-site scripting (XSS) flaws were found in Firefox. A malicious web page could display misleading information, allowing a user to unknowingly divulge 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 have been able to inject arbitrary HTML into a browsing session if the user reloaded a targeted site. (CVE-2007-0778)
Certain web content could overlay Firefox user interface elements such as the hostname and security indicators. A malicious web page could trick a user into thinking they were visiting a different site. (CVE-2007-0779)
Two flaws were found in Firefox's displaying of blocked popup windows. If a user could be convinced to open a blocked popup, it was possible to read arbitrary local files, or conduct a cross-site scripting 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. A malicious web page could set domain cookies for an arbitrary site, or possibly perform a cross-site scripting attack. (CVE-2007-0981)
Users of Firefox are advised to upgrade to this erratum package, containing Firefox version 18.104.22.168 which is not vulnerable to these issues.
