SeaMonkey is an open source Web browser, advanced email and newsgroup client, IRC chat client, and HTML editor.
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 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)
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.
