The Mozilla Foundation has discontinued support for the Mozilla Suite. This update deprecates the Mozilla Suite in Red Hat Enterprise Linux 3 in favor of the supported SeaMonkey Suite.

This update also resolves a number of outstanding Mozilla security issues:

Several flaws were found in the way Mozilla processed certain javascript actions. A malicious web page could execute arbitrary javascript instructions with the permissions of "chrome", allowing the page to steal sensitive information or install browser malware. (CVE-2006-2776, CVE-2006-2784, CVE-2006-2785, CVE-2006-2787)

Several denial of service flaws were found in the way Mozilla processed certain web content. A malicious web page could crash firefox or possibly execute arbitrary code. These issues to date were not proven to be exploitable, but do show evidence of memory corruption. (CVE-2006-2779, CVE-2006-2780)

A double-free flaw was found in the way Mozilla-mail displayed malformed inline vcard attachments. If a victim viewed an email message containing a carefully crafted vcard it could execute arbitrary code as the user running Mozilla-mail. (CVE-2006-2781)

A cross site scripting flaw was found in the way Mozilla processed Unicode Byte-order-Mark (BOM) markers in UTF-8 web pages. A malicious web page could execute a script within the browser that a web input sanitizer could miss due to a malformed "script" tag. (CVE-2006-2783)

A form file upload flaw was found in the way Mozilla handled javascript input object mutation. A malicious web page could upload an arbitrary local file at form submission time without user interaction. (CVE-2006-2782)

A denial of service flaw was found in the way Mozilla called the crypto.signText() javascript function. A malicious web page could crash the browser if the victim had a client certificate loaded. (CVE-2006-2778)

Two HTTP response smuggling flaws were found in the way Mozilla processed certain invalid HTTP response headers. A malicious web site could return specially crafted HTTP response headers which may bypass HTTP proxy restrictions. (CVE-2006-2786)

A double free flaw was found in the way the nsIX509::getRawDER method was called. If a victim visited a carefully crafted web page it could execute arbitrary code as the user running Mozilla. (CVE-2006-2788)

Users of Mozilla are advised to upgrade to this update, which contains SeaMonkey version 1.0.2 that is not vulnerable to these issues.
