(CVE-2008-0412, CVE-2008-0413, CVE-2008-0415, CVE-2008-0419)
Several flaws were found in the way Firefox displayed malformed web
content. A webpage containing specially-crafted content could trick a user
into surrendering sensitive information. (CVE-2008-0591, CVE-2008-0593)
A flaw was found in the way Firefox stored password data. If a user saves
login information for a malicious website, it could be possible to corrupt
the password database, preventing the user from properly accessing saved
password data. (CVE-2008-0417)
A flaw was found in the way Firefox handles certain chrome URLs. If a user
has certain extensions installed, it could allow a malicious website to
steal sensitive session data. Note: this flaw does not affect a default
installation of Firefox. (CVE-2008-0418)
A flaw was found in the way Firefox saves certain text files. If a
website offers a file of type "plain/text", rather than "text/plain",
Firefox will not show future "text/plain" content to the user in the
browser, forcing them to save those files locally to view the content.
