RHSA-2009:1531 - Security Advisory

Topic

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.
