Updated seamonkey packages that fix several security bugs in the mozilla
package are now available for CentOS Linux 3.
This update has been rated as having critical security impact by the Red
Hat Security Response Team.
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 CentOS Linux 3 in favor
of the supported SeaMonkey Suite.
This update also resolves a number of outstanding Mozilla security issues:
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,
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)
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
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
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.
