CentOS 4 : seamonkey (CESA-2009:1431)
Critical Nessus Plugin ID 40933
SynopsisThe remote CentOS host is missing one or more security updates.
DescriptionUpdated SeaMonkey packages that fix several security issues are now available for Red Hat Enterprise Linux 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, 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)
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)
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.
SolutionUpdate the affected seamonkey packages.
