(RHSA-2007:0402) Critical: seamonkey security update

SeaMonkey is an open source Web browser, advanced email and newsgroup
client, IRC chat client, and HTML editor.

Several flaws were found in the way SeaMonkey processed certain malformed
JavaScript code. A web page containing malicious JavaScript code could
cause SeaMonkey to crash or potentially execute arbitrary code as
the user running SeaMonkey. (CVE-2007-2867, CVE-2007-2868)

A flaw was found in the way SeaMonkey handled certain FTP PASV commands. A
malicious FTP server could use this flaw to perform a rudimentary port-scan
of machines behind a user’s firewall. (CVE-2007-1562)

Several denial of service flaws were found in the way SeaMonkey handled
certain form and cookie data. A malicious web site that is able to set
arbitrary form and cookie data could prevent SeaMonkey from
functioning properly. (CVE-2007-1362, CVE-2007-2869)

A flaw was found in the way SeaMonkey processed certain APOP authentication
requests. By sending certain responses when SeaMonkey attempted to
authenticate against an APOP server, a remote attacker could potentially
acquire certain portions of a user’s authentication credentials.
(CVE-2007-1558)

A flaw was found in the way SeaMonkey handled the addEventListener
JavaScript method. A malicious web site could use this method to access or
modify sensitive data from another web site. (CVE-2007-2870)

A flaw was found in the way SeaMonkey displayed certain web content. A
malicious web page could generate content that would overlay user
interface elements such as the hostname and security indicators, tricking
users into thinking they are visiting a different site. (CVE-2007-2871)

Users of SeaMonkey are advised to upgrade to these erratum packages, which
contain SeaMonkey version 1.0.9 that corrects these issues.
