(RHSA-2008:0103) Critical: firefox security update

Mozilla Firefox is an open source Web browser.

Several flaws were found in the way Firefox processed certain malformed web
content. A webpage containing malicious content could cause Firefox to
crash, or potentially execute arbitrary code as the user running Firefox.
(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.
(CVE-2008-0592)

Users of firefox are advised to upgrade to these updated packages, which
contain backported patches to resolve these issues.
