Critical Nessus Plugin ID 60665
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionCVE-2009-2409 deprecate MD2 in SSL cert validation (Kaminsky)
CVE-2009-2408 firefox/nss: doesn't handle NULL in Common Name properly
CVE-2009-2654 firefox: URL bar spoofing vulnerability
CVE-2009-3072 Firefox 3.5.3 3.0.14 browser engine crashes
CVE-2009-3076 Firefox 3.0.14 Insufficient warning for PKCS11 module installation and removal
CVE-2009-3077 Firefox 3.5.3 3.0.14 TreeColumns dangling pointer vulnerability
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.
After installing the update, SeaMonkey must be restarted for the changes to take effect.
SolutionUpdate the affected packages.
