(RHSA-2006:0578) seamonkey security update (was mozilla)

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 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.
