CentOS 3 / 4 : seamonkey (CESA-2009:1531)
Critical Nessus Plugin ID 42296
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 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, email and newsgroup client, IRC chat client, and HTML editor.
A flaw was found in the way SeaMonkey creates temporary file names for downloaded files. If a local attacker knows the name of a file SeaMonkey is going to download, they can replace the contents of that file with arbitrary contents. (CVE-2009-3274)
A flaw was found in the way SeaMonkey handles text selection. A malicious website may be able to read highlighted text in a different domain (e.g. another website the user is viewing), bypassing the same-origin policy. (CVE-2009-3375)
A flaw was found in the way SeaMonkey displays a right-to-left override character when downloading a file. In these cases, the name displayed in the title bar differs from the name displayed in the dialog body. An attacker could use this flaw to trick a user into downloading a file that has a file name or extension that differs from what the user expected. (CVE-2009-3376)
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-2009-3380)
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.
