CESA-2007:0402: seamonkey security update

Description

Updated seamonkey packages that fix several security bugs are now available for CentOS 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. 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.
