Security Advisory - RHSA-2009:1531-1
------------------------------------------------------------------------------
Summary:
Critical: seamonkey security update

Updated seamonkey packages that fix several security issues are now
available for Red Hat Enterprise Linux 3 and 4.

This update has been rated as having critical security impact by the Red
Hat Security Response Team.

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

A flaw was found in the way SeaMonkey creates temporary file names for
downloaded files. If a local attacker knows the name of a file SeaMonkey is
going to download, they can replace the contents of that file with
arbitrary contents. (CVE-2009-3274)

A heap-based buffer overflow flaw was found in the SeaMonkey string to
floating point conversion routines. A web page containing malicious
JavaScript could crash SeaMonkey or, potentially, execute arbitrary code
with the privileges of the user running SeaMonkey. (CVE-2009-1563)

A flaw was found in the way SeaMonkey handles text selection. A malicious
website may be able to read highlighted text in a different domain (e.g.
another website the user is viewing), bypassing the same-origin policy.
(CVE-2009-3375)

A flaw was found in the way SeaMonkey displays a right-to-left override
character when downloading a file. In these cases, the name displayed in
the title bar differs from the name displayed in the dialog body. An
attacker could use this flaw to trick a user into downloading a file that
has a file name or extension that differs from what the user expected.
(CVE-2009-3376)

Several flaws were found in the processing of malformed web content. A web
page containing malicious content could cause SeaMonkey to crash or,
potentially, execute arbitrary code with the privileges of the user running
SeaMonkey. (CVE-2009-3380)

All SeaMonkey users should upgrade to these updated packages, which correct
these issues. After installing the update, SeaMonkey must be restarted for
the changes to take effect.
