| Descripción: | Summary:
The remote host is missing an update for the 'seamonkey'
package(s) announced via the referenced advisory.
Vulnerability Insight:
SeaMonkey is an open source Web browser, email and newsgroup client, IRC
chat client, and HTML editor.
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-2009-3072, CVE-2009-3075)
A use-after-free flaw was found in SeaMonkey. An attacker could use this
flaw to crash SeaMonkey or, potentially, execute arbitrary code with the
privileges of the user running SeaMonkey. (CVE-2009-3077)
Dan Kaminsky discovered flaws in the way browsers such as SeaMonkey handle
NULL characters in a certificate. If an attacker is able to get a
carefully-crafted certificate signed by a Certificate Authority trusted by
SeaMonkey, the attacker could use the certificate during a
man-in-the-middle attack and potentially confuse SeaMonkey into accepting
it by mistake. (CVE-2009-2408)
Descriptions in the dialogs when adding and removing PKCS #11 modules were
not informative. An attacker able to trick a user into installing a
malicious PKCS #11 module could use this flaw to install their own
Certificate Authority certificates on a user's machine, making it possible
to trick the user into believing they are viewing a trusted site or,
potentially, execute arbitrary code with the privileges of the user running
SeaMonkey. (CVE-2009-3076)
A flaw was found in the way SeaMonkey displays the address bar when
window.open() is called in a certain way. An attacker could use this flaw
to conceal a malicious URL, possibly tricking a user into believing they
are viewing a trusted site. (CVE-2009-2654)
Dan Kaminsky found that browsers still accept certificates with MD2 hash
signatures, even though MD2 is no longer considered a cryptographically
strong algorithm. This could make it easier for an attacker to create a
malicious certificate that would be treated as trusted by a browser. NSS
(provided by SeaMonkey) now disables the use of MD2 and MD4 algorithms
inside signatures by default. (CVE-2009-2409)
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.
Affected Software/OS:
seamonkey on CentOS 3
Solution:
Please install the updated packages.
