Various flaws have been reported that allow an attacker to execute arbitrary code with user privileges by tricking the user into opening a malicious email containing JavaScript. Please note that JavaScript is disabled by default for emails, and it is not recommended to enable it. (CVE-2006-4253, CVE-2006-4565, CVE-2006-4566, CVE-2006-4571)

The NSS library did not sufficiently check the padding of PKCS #1 v1.5 signatures if the exponent of the public key is 3 (which is widely used for CAs). This could be exploited to forge valid signatures without the need of the secret key. (CVE-2006-4340)

Jon Oberheide reported a way how a remote attacker could trick users into downloading arbitrary extensions with circumventing the normal SSL certificate check. The attacker would have to be in a position to spoof the victim's DNS, causing them to connect to sites of the attacker's choosing rather than the sites intended by the victim. If they gained that control and the victim accepted the attacker's cert for the Mozilla update site, then the next update check could be hijacked and redirected to the attacker's site without detection.
(CVE-2006-4567)

Georgi Guninski discovered that even with JavaScript disabled, a malicous email could still execute JavaScript when the message is viewed, replied to, or forwarded by putting the script in a remote XBL file loaded by the message. (CVE-2006-4570).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The installed version of Firefox is affected by various security issues, some of which may lead to execution of arbitrary code on the affected host subject to the user's privileges.

Updated SeaMonkey packages that fix several security bugs are now available for Red Hat Enterprise Linux 2.1, 3, and 4.

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.

Two flaws were found in the way SeaMonkey processed certain regular expressions. A malicious web page could crash the browser or possibly execute arbitrary code as the user running SeaMonkey. (CVE-2006-4565, CVE-2006-4566)

A flaw was found in the handling of JavaScript timed events. A malicious web page could crash the browser or possibly execute arbitrary code as the user running SeaMonkey. (CVE-2006-4253)

Daniel Bleichenbacher recently described an implementation error in RSA signature verification. For RSA keys with exponent 3 it is possible for an attacker to forge a signature that would be incorrectly verified by the NSS library. SeaMonkey as shipped trusts several root Certificate Authorities that use exponent 3. An attacker could have created a carefully crafted SSL certificate which be incorrectly trusted when their site was visited by a victim.
(CVE-2006-4340)

SeaMonkey did not properly prevent a frame in one domain from injecting content into a sub-frame that belongs to another domain, which facilitates website spoofing and other attacks (CVE-2006-4568)

A flaw was found in SeaMonkey Messenger triggered when a HTML message contained a remote image pointing to a XBL script. An attacker could have created a carefully crafted message which would execute JavaScript if certain actions were performed on the email by the recipient, even if JavaScript was disabled. (CVE-2006-4570)

A number of flaws were found in SeaMonkey. A malicious web page could crash the browser or possibly execute arbitrary code as the user running SeaMonkey. (CVE-2006-4571)

Users of SeaMonkey or Mozilla are advised to upgrade to this update, which contains SeaMonkey version 1.0.5 that corrects these issues.

For users of Red Hat Enterprise Linux 2.1 this SeaMonkey update obsoletes Galeon. Galeon was a web browser based on the Mozilla Gecko layout engine.

A number of security vulnerabilities have been discovered and corrected in the latest Mozilla Firefox program, version 1.5.0.7.

This update provides the latest Firefox to correct these issues.
